Titanium alloy wire has acid-washed surface, bright surface and carburized surface.

Titanium alloy is a stable carbide with high hardness. The growth of the carbonized layer between titanium and carbon is determined by the diffusion rate of titanium in the carbonized layer.

Small solubility of carbon in titanium, 850 x: when a total of 0.3%, and about to 0.1% at 600 c B due to the smaller the solubility of carbon in titanium so basically only by titanium carbide layer and the bottom sediments domain to achieve the goal of surface hardening. Must be conducted under the condition of removing oxygen carburizing, because it is suitable for powder of steel carburizing is commonly used for the carbon monoxide and oxygen of the surface of the carbon monoxide and form the surface layer of hardness of 2700 mpa and 2700 mpa, and mesh. Peeling off easily.

In contrast, a thin layer of titanium carbide may be formed when carbon is carburized in charcoal under deoxidization or decarburization. The hardness of this layer is 32OUOMPa, which is consistent with the hardness of titanium carbide. The depth of the carburizing layer is roughly greater than that of nitriding at the same conditions. Under the condition of oxygen enrichment, oxygen absorption must be considered to affect the depth of hardening. Only under the condition of thin layer thickness, in a vacuum or argon - people carbon powder to form methane atmosphere enough adhesion strength by contrast, with gas carburizing agent may be especially hard and good bonding formation of titanium carbide hardening layer. At the same time, the hardened shows formed at the temperature between 950T and 10201 are between 50fim and between. With the increase of thickness, titanium carbide layer become more brittle, and tend to spalling t in order to avoid because rui alkanes decomposition and carbon inclusion of shooting, titanium carbide layer should be adopted about the rules of the volume fraction of 2% Rachel alkanes dose of additives in inert gas for gas carburizing. Low surface hardness is formed when methane is carburized with propane additives. When the adhesion of wood to the gas carburized propane is achieved under the condition of the OkPa, although the thickness of the hardened layer is very thin, it has the best wear resistance. Hydrogen is absorbed in the condition of the gas carburizing agent, but it has to be removed when the vacuum is annealed.
