摘要：

Microstructural, tribological, and electrochemical studies have been used to investigate the complex interaction between coating weight and the steel substrate in determining the quality of hot-dip galvanized coatings. Coatings with higher weight exhibit better corrosion resistance due to the formation of a thicker passivation layer during long-term exposure, making them suitable for aggressive environments, though mechanical strength may be reduced due to the influence of the ductile ) phase. The choice of steel substrate has little influence on the coating's appearance, corrosion resistance. The results of this study enable the design of high-quality coatings that balance corrosion resistance, mechanical strength.
