Microstructure and Wear Properties of Self-Lubricating H-BN/Ni Coating by Laser Cladding

Abstract:

Article Preview

Self-lubricating h-BN/Ni coating was prepared on a medium carbon steel substrate by CO2 laser cladding using a powder mixture of NiCrBSi+5%h-BN(wt.%). Microstructures and phase structure of the coating were analyzed using SEM, EDS and XRD. Wear tests were carried out using a M100 pin-on-ring wear tester. The results show that h-BN/Ni coating has much superior war resistance and noticeably lower fiction coefficient under dry sliding wear test conditions.
