Problems solved by technology

[0002] Usually, after titanium products are made, the surface needs to be treated, but after the traditional surface treatment method, the surface has the following disadvantages: there are obvious polishing lines and welding lines, and it is easy to stick to the hand lines after sandblasting. Uniformity leads to non-uniform color, color difference, etc.

Abstract

A surface treatment method used for titanium molecule fission of a titanium product is disclosed. The method includes (1) a step of polishing the titanium product and removing oil stains; (2) a step of putting the polished titanium product into a vacuum heat treatment furnace and maintaining a negative pressure of 8-10 Pa; and (3) a step of raising the temperature in the vacuum heat treatment furnace to 1000-1500 DEG C, maintaining the temperature for 1-5 h, then decreasing the high temperature in a range of 1000-1500 DEG C to 100-500 DEG C, feeding air into the furnace, maintaining the temperature for 0.5-4 h and opening the furnace. According to the method, impurities in the titanium product are removed through high temperature so that environment protection environments are met and application safety is high. After treatment, polishing lines and welding lines are absent, hand lines are not attached to the product, product scratches, dropping breakage, and the like are prevented, color is unified and free of color differences, surfaces are flat, smooth and beautiful, surface hardness of the titanium product is increased, and the overall performance of the product is improved.

Description

technical field [0001] The invention relates to a surface treatment technology, in particular to a surface treatment method for titanium molecular fission of titanium products. Background technique [0002] Usually, after titanium products are made, the surface needs to be treated, but after the traditional surface treatment method, the surface has the following disadvantages: there are obvious polishing lines and welding lines, and it is easy to stick to the hand lines after sandblasting. Uniformity leads to non-uniform color, color difference and so on. Contents of the invention [0003] In view of the above deficiencies, the purpose of the present invention is to provide a surface treatment method for titanium molecular fission of titanium products, which can remove impurities in titanium products through high temperature, meet environmental protection requirements, and have high safety in use; at the same time, there is no polishing pattern and The phenomenon of weldi...
