Ni-MoS2 Self-lubricating Composite Coating Prepared by Jet Electrodeposition on Aluminum Alloy Formed by SLM
Ni-MoS2 self-lubricating composite coating was prepared by jet electrodeposition on aluminum alloy formed by SLM.The friction and wear tester was used to evaluate the influence of MoS2 concentration in the plating solution on the friction and wear properties of the Ni-MoS2 self-lubricating composite coating.The results show that co-deposited MoS2 particles can effectively reduce the friction coefficient and wear rate of the Ni-MoS2 self-lubricating composite coating.Compared with that of pure Ni coating,the friction coefficient and wear rate of Ni-MoS2 self-lubricating composite coating and 316L steel ball on the grinding are significantly reduced,the friction coefficient reduces from 0.51 to 0.12,and the wear rate reduces from 0.41 mg/m to 0.11 mg/m,which can provide references for improving the tribological properties of aluminum alloy formed by SLM.
