Powder sherardizing agent, anti-corrosion metal part, and sherardizing method

Abstract

The disclosure provides a powder sherardizing agent, anti-corrosion metal part and sherardizing method. The powder sherardizing agent in parts by mass includes 20-100 parts of a metal powder, 40-80 parts of a dispersing agent, 0.2-5 parts of decomposing agent. The metal powder includes 60-97 parts of zinc powder and 3-40 parts of magnesium powder. The powder sherardizing agent provided by this disclosure can realize the infiltration of magnesium during the sherardizing process. Zinc and magnesium can form a zinc-magnesium alloy phase with high corrosion resistance, thereby greatly improving the corrosion resistance of the infiltration layer. The sherardizing method provided by this disclosure has the advantages of simple operation, convenient use, low cost, high economic benefit, and wide application range.
