Zn–Fe and Y‐modified Zn–Fe coatings on 42CrMo steel via pack cementation
Source abstract
Abstract
Abstract Zn–Fe and Y‐modified Zn–Fe coatings were prepared on 42CrMo steel through pack cementation processes at 370, 390 and 410 °C for 4 h. Y modification was achieved through the co‐deposition of Zn and Y 2 O 3 . The effects of Y modification on microstructure, formation and corrosion behavior of the Zn–Fe coating were investigated. The coating thickness increased with an increase in temperature. The Y‐modified Zn–Fe coating was thicker than the plain Zn–Fe coating. Both the Zn–Fe coating and Y‐modified Zn–Fe coating showed single‐layered structures, but the overall microstructure was improved by Y modification. The activation energies for Zn–Fe coating and Y‐modified Zn–Fe coating were 113.15 and 80.65 kJ·mol −1 , respectively. The Zn–Fe coating consisted of FeZn 13 and Fe 11 Zn 40 phases. The effects of Y modification on the corrosion behavior of the Zn–Fe coating were evaluated through an immersion test and polarization measurements. The results showed that the corrosion resistance was improved by Y modification.
