Abstract

The hot stamping technology of ultra-high-strength boron steel is an effective way to lighten the weight of automobiles. High-strength steel zinc-iron (GA) coated plates have the dual roles of barrier and cathodic protection, and have a broad application prospect in the field of boron steel hot stamping. How to control the heat treatment process to achieve the optimal balance of the plating organization, protective properties and matrix properties is the core issue in industrial application. The influence mechanism of different pre-oxidation time and austenitization temperature holding time on the matrix properties and plating organization characteristics under the stepped rapid heating process was investigated. Firstly, the polarization curves were obtained through electrochemical characterization tests to qualitatively evaluate the cathodic protection performance of zinc-iron plating in different states; then the macroscopic corrosion behaviors of zinc-iron plated plates in the original state, plated plates and bare plates under different heating processes were comparatively analyzed through neutral salt spray tests; finally, the range of rapid heating processes for plating in obtaining better corrosion resistance was summarized in combination with the high-temperature characteristics of plated plates under the rapid heating process.
