Abstract

The invention discloses a method for mechanically plating zinc on a surface of a steel piece. The method comprises the following operation steps that 1, the surface of the prepared steel piece is cleaned, then the steel piece is added into a mechanical zinc plating roller and is added with an activating solution, and a rotating cylinder is started to process the mixture for 5-7 minutes; and 2, a zinc plating solution is continuously added into the mechanical zinc plating roller, and the rotating cylinder is starting to process the mixture for 25-30 minutes to obtain a finished product. The method for mechanically plating zinc on the surface of the steel piece has the advantages of being is stable in process and can realize continuous large-scale production; the prepared steel piece has excellent oxidation resistance and corrosion resistance, the adhesive force of a film layer of the steel piece is relatively high, the surface film layer is uniformly distributed, and excellent wear resistance of the the film layer is achieved; the obtained piece has no hydrogen embrittlement phenomenon; and therefore the quality of the steel piece is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of surface treatment of iron and steel parts, and in particular relates to a method for mechanically galvanizing the surface of iron and steel parts. Background technique [0002] Mechanical galvanizing is a process that uses chemical adsorption and mechanical collision to deposit metal zinc powder on the surface of the workpiece to form a coating at normal temperature and pressure. Compared with traditional hot-dip galvanizing and electro-galvanizing, it has the advantages of low energy consumption in the production process. It has the advantages of less environmental pollution and is a clean and low-consumption galvanizing technology. However, in the prior art, mechanical galvanizing has poor coating uniformity, and hydrogen embrittlement of workpieces often occurs. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a method for mechanically...
