I ever spoke of in my article, I believe finishing kind the magazine often should mention a metal its itself. Be based on this, "Clean time " the earliest two column report concerns with the metal: One is about aluminium (in October 2006) ; Another is stainless steel (in April 2006) . This period " clean time " what column discusses is metallic titanium. Special material titanium is a kind of good stuff that can satisfy certain and special requirement. People often does not use metallic titanium, because stainless steel stores marvellously,measure inferior. In all special requirements, the energy that of be the first to be affected is it, the rate of weight tall, density is low, the weight that compares steel is average low 40% ; The thermal stability below freeboard temperature is strong, have aseismatic function, fatigue resistance can, the corrosion resistance that compares stainless steel at the same time is stronger. Titanium alloy is the important material that aerospace domain makes crucial part normally. They also reach ballproof collar region with nautical, chariot, artillery in the application of other sphere euqally extensive. Titanium is the commonly used material in material of deep well casing of surgical transplanting operation and oil field, because titanium alloy quality is light, taller than stainless steel hardness. Titanium can apply at human body because it is avirulent to human body,embedded content is harmless, still have concentrated oxidation layer, after embedded human body can good compatible. As a result of the existence of oxidation coating, titanium constituent is had than stainless steel finished products better fight corrode ability. With rolled steel, the production of titanium metal also provides flexibility quite, the appearance that can be cast by relaxed ground because of it or forgings. The function of the metallic titanium that expresses 1 pair of different level had a description. 2 oxygen are the main element that controls intensity of blame alloy titanium. The density of special function titanium is 4540 kilogram about / every stere, and the density of steel is 2710 kilogram / every stere; The stretch model quantity of titanium is 110 × 109 Pascal, the stretch model quantity of steel is 210 × 109 Pascal. So titanium metal and steel are in Nextpage there is bigger deflection below identical load action. Pure titanium metal can pass cold rolling to make its ply decreases below room temperature 90% -- won't produce burst. Watch 2 gave out of metallic physics function compare data 3. If titanium can offer so many advantage and treatment function does not have adverse element, so people can apply it in all domains. But people did not do so: Annual the titanium gross that the whole world uses is pound of a few ten million, and the use volume with annual stainless steel exceeds billion pound. The main drawback of titanium is its processability. When undertaking machining to steel, the quantity of heat that cutting process produces can be followed cut bits to send out; But when undertaking machining to titanium, quantity of heat maintains centrally in tool interior or cutting tool brim. Cutting performance is bad it is at least by undermentioned 3 reasons cause, because of titanium: ● thermal conductivity is poor (have copper only 3% ) . The quantity of heat of the generation in cutting process cannot carry machine equipment or the component sends out; Quantity of heat increases continuously in cutting position, achieve 2000 Zuo even sometimes, the 4 cutting tools that contact to it will be rapid passivation, this makes the circumstance becomes more flooey. Use passivation tool, its brim can produce more quantity of heat, shorten further the life of the tool. ● titanium has very tall flexibility (low standard is measured) . Below cutting pressure, the stretch meeting of material makes material is played from cutting tool place piece, the mutual clash that caused the brim so (is not across and cut) 5, raised the temperature that coefficient of friction lifted cutting is in further. Process of ● general cutting can produce sclerosis. Carbide tool cannot be cut wear thick sclerotic stuff, and the process that still can accelerate sclerosis. The liquid that exists when tool of use carbon steel makes its wear-resisting, Jiang Ren, and adiabatic -- although these function want,increase through additional coating ability. The solution of the 2nd part of the infuse in undesirable treatment is to handle tool surface and the refrigerant all round to reach drossy. Solution of the 3rd part is to use the service life that accepts a tool to have a few hours only this be related is solid. Treatment is undesirable the destruction that cause is the surface produces tiny flaw normally, edge is raised reach plasticity to be out of shape; Get the area that heating power affects; Drawing remains stress. Its result is very crucial, because reduced fatigue intensity,reach fight corrode ability. Solder once most person thinks, soldering to the Tig6 of titanium is approximately impossible. Now, still somebody thinks so. Inferior solder puts through the color of the multicoloured that often can produce yellow, blue close piece. The welding line of admirable titanium shows freezing mercuric scene it seems that: Give off light and can reflex 7, 8. The high energy of titanium of careful Trojan horse - weight rate, biology laziness and tall corrosion resistance can be the reason that attracts people to use it. But it is difficult to machine and solder the use of the cutting rate that limitted a tool, lubricant and caloric move, this must be designed drossy move except the system, need to consider much thicker drossy ability to move from inside all tools except. If you more be happy to use former, so you need to learn how to handle latter. In 20 years of in the past, user and manufacturer are 9 what such doing. The essence of titanium metal acts the role of medical transplanting to ask to people the metallic titanium to embedded human body undertakes finishing -- had jumped over glossily more. Poriferous embedded body is the breeding ground that the bacterium causes. Can act the role of besmear Fu through essence of much measure large-scale or extremely smooth essence is acted the role of is centrifugal bucket system will come true. Latter perhaps is the quickest and effective method, also can use porcelain qualitative medium. Additionally one kind of commonly used method is to electroanalysis polishing, in recent years this kind of method is become but reduplicative commercializes an operation. Proposal user discriminates a supplier seriously, ensure electroanalysis high gradely polishing effect. Exorbitant acceptance is OK blurt out and say, because the practice is undeserved,not be, the result that should see special purpose however how. The zincous oxidation form of the titanium of oxidation of chromatic positive pole of titanium has two kinds commonly: Alkalescent positive pole oxidizes (PH is more than 12) in can producing project application thick, of wear-resisting, fight tatty surface. Acidity or neuter and zincous oxidation can produce the diffractive coating with very thin and diversiform color (coloring) , can use in adornment sex gem and similar application, see a picture please 2. But other operation detail need are decided according to the client's demand, electroanalysis polishing also needs such. Oxalic acid, phosphoric acid (Coke Cola) , ammonium sulfate and natrium of phosphoric acid hydrogen are used to normally in all sorts of operation conditions -- undertake oxidation is handled decorating sexual positive pole below voltage of time, temperature, commutate. Dc is the payoff that colour chooses normally; Engaging time is the payoff of colour ply. My overall proposal is the user should add the detail that notices other user puts forward more, because of to memorialist character, the proposal that they offer is a basis their spare parts dimension, appearance, quality, alloy, finishing, experience, equipment, eletroplate of groovy characteristic and the color decision that its expect. My specific proposal is: (1) enjoy among them fun, oneself have a test 10; (2) contract of custom-built and zincous oxidation; (3) get license from supplier place. Fix a price now, the price of titanium ingot is every pound 11 dollars left and right sides. Two years ago, or under 4 dollars. This one change means the whole world to begin get warm again after a cold spell to the demand of the commodity such as copper, iron. The price of titanium is by the purity of alloy and metal, amount, structure (pulverous, ingot, piece shape, form or tubal shape) and standards will decide. The price of the alloy in cosmic aviation technology and special purpose may exceed 100 dollars every pound. If titanium treatment can be easier, so cast will cheaper. Summed up this one column to respond to your demand. If you do not need the special strength that titanium place has, weight rate and corrosion resistance can, so perhaps you need not read this article. On the other hand, if you need to understand those good points of the titanium that speaks of in article only, so, you need to be read roughly only it is OK to read article content. CNC Milling
