Do you deal with the surface of titanium wire carburizing?


Titanium wire forms a higher hardness stabilized carbide with carbon. The growth of the carbonized layer between titanium and carbon is determined by the rate of diffusion of titanium in the carbonized layer. So, titanium wire carburizing surface treatment you will? Titanium wire production plant - Baoji City Feiteng metal materials to teach you.

The solubility of carbon in titanium is small, at a total of 0.3% at 850X and about 0.1% at 600 C. Since carbon has a small solubility in titanium, it is essentially only through the titanium carbide layer and its lower Sedimentary layer to achieve the purpose of surface hardening. It is necessary to carry out carburizing under the condition of removing oxygen because the hardness of the surface layer of the powder suitable for carburized carbon is about 2700 MPa and 8500 MPa against the surface of carbon monoxide or oxygen-containing carbon monoxide, and it is easy to peel off.

In contrast to this, under the conditions of deoxidation or decarburization, a thin layer of titanium carbide may be formed when carburizing in charcoal. The hardness of this layer is 32OUOMPa, in line with the hardness of titanium carbide. The depth of the carburized layer is substantially greater than the depth of the nitriding layer when nitrogen is nitrided under the same conditions. Under oxygen enrichment conditions, the absorption of oxygen must be taken into account to affect the hardening depth. It is possible to form sufficient adhesion strength in a vacuum or argon-methane atmosphere in a very thin layer thickness condition. The use of a gas carburizing agent may form a particularly hard and good bondability Of titanium carbide hardened layer. While the hardening exhibited under the conditions of temperature between 950T: and 10201: between 50fim and. With the increase in layer thickness, the titanium carbide layer becomes brittle and tends to peel off. In order to avoid the inclusions of carbons due to the decomposition of the dealkane, the titanium carbide layer is infiltrated, and a volume fraction of 2% Dosage Additives Gase the gas in an inert gas. When the use of propane additives and the use of methane carburizing when the formation of a lower surface hardness. When the gas is carburized with propane, the thickness of the hardened layer is measured, but it has the best wear resistance. In the use of gas-type carburizing agent under the conditions of hydrogen absorption, but in the vacuum annealing but had to re-remove it.
