Titanium wire
author:Admin    date:08/01     Number of Attentions:246    
Pure titanium is a silver-white metal with many excellent properties. Titanium has a density of 4.54g/cm3, 43% lighter than steel and slightly heavier than the well-known light metal magnesium. The mechanical strength is almost the same as that of steel, twice as much as that of aluminium and five times as much as that of magnesium. Titanium has high temperature resistance, melting point 1942K, nearly 1000K higher than gold and nearly 500K higher than steel.

Surface Treatment of Titanium Wire Carburizing
Titanium wire forms a stable carbide with high hardness with carbon. The growth of the carbide layer between titanium and carbon is determined by the diffusion rate of titanium in the carbide layer.
The total solubility of carbon in titanium is 0.3% at 850X: and about 0.1% at 600C. Because of the low solubility of carbon in titanium, surface hardening is basically achieved only through the deposition of titanium carbide layer and its underlying pinch area. Carburizing must be carried out under the condition of deoxidization, because the hardness of surface layer formed by common carburized powders on the surface of carbon monoxide or oxygen-containing carbon monoxide reaches 2700 MPa and 8500 MPa, and it is easy to peel off.
In contrast, under deoxidization or decarbonization conditions, a thin layer of titanium carbide may be formed when carburizing in charcoal. The hardness of this layer is 320 UOMPa, which is in line with the hardness of titanium carbide. The depth of the carburized layer is greater than that of the nitrided layer under the same conditions. Under the condition of oxygen enrichment, the influence of oxygen absorption on hardening depth must be considered. Only under very thin layer thickness, carburizing carbon powder in vacuum or in argon-methane atmosphere can form enough adhesion strength, compared with this, using gas carburizing agent may form a particularly hard and good bonding titanium carbide hardening layer. At the same time, the hardening formed at the temperature between 950T: and 1021: ranges from 50fim to 50fim. With the increase of layer thickness, the TiC layer becomes brittle and tends to exfoliate t. In order to avoid the inclusions of carbon penetrating TiC layer due to the decomposition of ruthene, Gas Carburization in inert gas should be carried out with a prescribed dose additive of about 2% ruthene. Low surface hardness is formed when methane is carburized with propane additive. When gas carburized propane is used when the bonding strength reaches OkPa, although the thickness of hardened layer measured is very thin, it has the best wear resistance. Hydrogen is absorbed under the condition of gas carburizing agent, but it has to be removed again during vacuum annealing.
