In-situ Cu Coating on Steel Surface after Oxidizing at High Temperature

In-situ Cu Coating on Steel Surface after Oxidizing at High Temperature

Almost all copper in scrap steel is recovered, so research on copper-bearing steel has profound practical significance. The surface enrichment of copper occurs in all copper-bearing steels studied in this paper after being heated at high temperature. In-situ oxidation-induced copper coatings were di...
