Corrosion Resistance, Friction and Wear Characteristics in Seawater of Alloy Steel with Surface Modification Layers Produced by Friction Reforming Technique and Carburizing

Abstract

Our research team applied surface modification processes to alloy steel to improve its corrosion and wear resistance, especially in seawater. The processes included fine powder intrusion, post processing, carburizing and zinc coating. Two different kinds of powder, Cr and Mo, were used for powder intrusion. After the modification, corrosion and friction tests were conducted on the specimens. The results showed that the modified materials demonstrated excellent wear resistance and anti-corrosion properties.
