Abstract

The invention discloses an accelerant for titanium powder mechanochemical deposition and application, which belong to the technical field of titanium plating on steel matrixes. The accelerant comprises the following raw materials in percentage by mass: 10%-25% of ammonium bifluoride, 5%-12% of zinc sulfate (ZnSO4.7H2O), 6%-15% of polyethylene glycol, 3%-8% of nickel aminosulfonate, 3%-8% of emulsifier, 2%-5% of sodium hypophosphite, 0.5%-6% of inorganic strong acid and the balance of water. When the accelerant is prepared, water and inorganic strong acid are firstly added into a container, andthen ammonium bifluoride, zinc sulfate, nickel aminosulfonate, polyethylene glycol and an emulsifying agent are added. The accelerant disclosed by the invention is used for preparing a mechanochemical deposition titanium plating layer on a steel matrix, the titanium powder and the accelerant disclosed by the invention are added together in use, the components of the accelerant can activate the surface of the titanium powder, continuous and stable deposition of the titanium powder in a plating solution environment is realized, and finally, the titanium plating layer which is firm in combination and uniform in thickness is obtained on the surface of the matrix.

Description

technical field [0001] The invention relates to an accelerator for mechanical chemical deposition of titanium powder and its application, and belongs to the technical field of surface protection, specifically, it belongs to the technical field of titanium plating on steel substrates. Background technique [0002] Compared with zinc, aluminum and their alloys, titanium has excellent corrosion resistance, and its corrosion resistance can reach dozens of times that of zinc and aluminum protective layers. It is very suitable for surface protection of equipment components and connectors. However, due to the chemical properties of titanium and other reasons, metal titanium cannot be electroplated in an aqueous solution, and can only be layered by molten salt electroplating, sputtering deposition, and spraying, and only sputtering deposition has been widely used, molten salt electroplating, Spraying is mostly in the research stage. [0003] Compared with traditional electroplatin...
