Gr2 ERTi-2 titanium wires with carburizing surface treatment

Analysis of the problem of how to carburize surface treatment of titanium wire? Pure titanium is a silver-white metal that has many excellent properties. Titanium wire forms a stable carbide with carbon with high hardness. The growth of the carbide layer between titanium and carbon is determined by the rate of diffusion of titanium in the carbide layer.
The solubility of carbon in titanium is small, totaling 0.3% at 850X: and falling to about 0.1% at 600C B Because of the small solubility of carbon in titanium, surface hardening is basically only achieved by the deposition of the titanium carbide layer and its underlying forsaken domain. Carburizing must be carried out under the condition of removing oxygen, because the surface hardness of the surface layer formed by applying the commonly used carburizing powder for steel against carbon monoxide or carbon monoxide surface containing oxygen reaches 2700MPa and 8500MPa, and eye. It flakes off easily.
