Surface treatment method for rivet assembly

The application provides a surface treatment method of a pull rivet assembly, which comprises the following steps: forming a zinc-aluminum coating on a pull rivet and a sleeve ring through a multiple film forming mode; wherein the material of the pull rivet is medium-carbon alloy structural steel, the material of the sleeve ring is low-carbon steel, the zinc content in the zinc-aluminum coating is 85%-95%, and the aluminum content in the zinc-aluminum coating is 5%-15%; and the zinc-aluminum coating is subjected to heat diffusion treatment to form an iron-zinc-aluminum alloy protective layer on the surface of the pull rivet and the sleeve ring. In the technical scheme, the zinc-aluminum coating is formed on the pull rivet and the sleeve ring through the multiple film forming mode, and the heat diffusion treatment mode is adopted, so that the zinc diffuses into the pull rivet and the sleeve ring, and the iron of the pull rivet and the sleeve ring diffuses into the zinc-aluminum coating, thereby forming the iron-zinc-aluminum alloy protective layer, improving the structural strength of the protective layer on the outer side of the pull rivet and the sleeve ring, improving the corrosion resistance, and improving the use effect of the pull rivet and the sleeve ring.

A production device and method of zinc powder for zinc infiltration process

This invention belongs to the field of zinc powder production technology, specifically a production equipment and method for zinc powder used in zinc diffusion processes. Addressing the problems of zinc powder oxidation and the inability to screen the produced zinc powder in existing technologies, the invention includes a base frame with a bottom box fixedly installed on top. Two electric push rods are symmetrically fixedly installed on the inner bottom wall of the bottom box, with their output shafts extending to the top of the bottom box and fixedly fitted with the same sealing ring. This invention allows the zinc powder or zinc vapor to be processed in a relatively closed environment during the cooling process to form zinc powder, thus avoiding oxidation. Furthermore, after zinc powder production, it enables sorting, facilitating convenient classification and packaging during practical use.
