Embodiment Construction

[0005] A preparation process of a titanium metal head, characterized in that: titanium alloy gas carburization is used, carburizing gas acetylene is cracked at high temperature to form active carbon atoms, and carbon atoms are used to diffuse on the surface of titanium alloy, and the carburizing temperature is controlled At 1500°C, the carburizing time is 2.5h, and the thickness of the obtained carburized layer is 300μm. The test equipment consists of high temperature vacuum carburizing furnace: gas, circulating pump, circulating water, special alloy plate, heater and vacuum pump. The carburizing furnace uses a molybdenum target as a heating source, and the temperature can be heated to 1900°C. Use ordinary mechanical pumps to vacuumize, and the vacuum degree can reach 12 -1 Pa.

Abstract

The invention relates to a preparing process for a titanium metal sealing end. The preparing method is characterized by adopting titanium alloy for gas carburizing, pyrolyzing carburized acetylene under high temperature to form active carbon atoms, and using the carbon atoms for diffusion on the surface of the titanium alloy, wherein a carburizing temperature is controlled to be 1500 DEG C, carburizing time is controlled to be 2.5h, and the thickness of an obtained carburizing layer is 300mu m. The preparing process has the characteristics that a workpiece should be kept clean and pollution-free always before heating and in a heating process, the manufacturing is simple and convenient, the weight is light, the product cost is low, the comprehensive mechanical properties are high, and wear resistance, corrosion resistance and high temperature resistance are realized.

Description

technical field [0001] The invention belongs to the field of machinery, and relates to a preparation process of a titanium metal head. Background technique [0002] Most of the heads are spinning or stamping, heated or not, the appropriate heating temperature and whether the formed head needs to be heat treated should be determined according to the specific situation, such as material performance status, head specifications, cold hardening degree and equipment capacity conditions, etc. Inadequate cleaning before and during heating. The polluted environment has a low yield rate, low production efficiency, and the inability to realize large-scale industrial production, which limits the application of this promising bearing material. Contents of the invention [0003] The purpose of the present invention is to solve the defects in the prior art, and to invent a preparation process for titanium metal heads, which is characterized in that: titanium alloy gas carburization is ...
