Research on Adhesion and Properties of Composite Coating on Aluminized Carbon Steel

Abstract

In this paper, we studied the adhesion and properties of the composite coating on aluminized carbon steel. The part of the review introduces the concept and application of aluminizing technology and composite coating on carbon steel, and the related research is summarized. In the professional content section, the aluminizing process of carbon steel, the preparation method and characteristics of the composite coating, and the evaluation method of composite coating performance are introduced. In the main body, we focused on the research content of aluminized structure and corrosion behavior of carbon steel and studied the adhesion, corrosion resistance, wear resistance, thermal stability, and microstructural properties of composite coatings on aluminized carbon steel. In addition, this study includes the bonding mechanism between the composite coating and the substrate, the corrosion protection mechanism of the composite coating, the wear resistance mechanism of the composite coating, the thermal stability of the composite coating, and the factors affecting the adhesion, corrosion resistance, wear resistance, thermal stability and microstructure of the composite coating. The results show that the composite coating after aluminizing treatment can effectively improve the surface properties of carbon steel. Different preparation methods and process conditions have a significant effect on the performance of the composite coating. This study is of great significance for understanding the properties and preparation of composite coatings after aluminizing treatment of carbon steel.
