Abstract

The invention discloses a powder surface treating agent, titanium and titanium alloy powder surface treatment method and composite powder. The powder surface treating agent comprises an organic polymer, a titanate coupling agent and an organic solvent, wherein the organic polymer is at least one of polystyrene and ABS (acrylonitrile butadiene styrene) plastic, the organic solvent is xylene or methylbenzene, the concentration of the organic polymer is 0.005-0.04g / mL, and the concentration of the titanate coupling agent is 0.001-0.004g / mL. The powder surface treating agent is used for carrying out surface treatment on titanium or titanium alloy powder, so that an organic matter coating layer is formed on the surface of the titanium or the titanium alloy powder, the increase of the oxygen content in the later use and transportation processes can be inhibited, the mechanical performance is improved, and the technical problems of poor activity and high cost in the application of the HDH titanium and titanium alloy powder in a high-end titanium product in the prior art are solved.

Description

technical field

[0001] The invention relates to the technical field of powder metallurgy, in particular to a powder surface treatment agent, a surface treatment method for titanium and titanium alloy powder, and a composite powder. Background technique

[0002] Titanium and titanium alloys are widely used in various fields such as aerospace, marine engineering, and medical materials because of their low density, high specific strength, good corrosion resistance, and good biocompatibility. However, the titanium and titanium alloys prepared by the traditional casting process are complicated, the material loss is large during secondary processing, and there are problems such as low production efficiency, high production cost, and difficulty in manufacturing parts with complex shapes, which seriously limit the industrialization of titanium and titanium alloys. application level. As an efficient, high-quality, precise and energy-saving near-end forming technology, powder metallu...
