Ag含量对Ni3Al基涂层宽温域摩擦学行为的影响

摘要/Abstract

摘要： 采用激光熔覆技术在310S奥氏体不锈钢表面制备了不同质量分数Ag固体润滑剂的Ni₃Al基复合涂层,考察了Ag质量分数(5%、10%、15%)对涂层相组成、显微硬度、摩擦学性能和磨损表面相组成的影响.结果表明:由于Ag的软质特性,复合涂层的显微硬度随其含量增加呈逐渐降低的趋势,当Ag质量分数达10%时涂层仍具有相对较高的显微硬度,约为198.37 HV.在Ni₃Al涂层中引入10% Ag可使涂层25~800 ℃内的摩擦系数由0.69~0.55降低至0.62~0.41,400~800 ℃内的磨损率由(2.27~1.60)×10^－5 mm³/(N·m)降低至(1.28~0.44)×10^－5 mm³/(N·m).复合涂层减摩能力的提升与25~400 ℃内软金属Ag的扩散迁移以及400~800 ℃内Ni₃Al和Ag的氧化产物协同润滑作用有关;而涂层抗磨能力的提升与其较高的机械强度和磨损表面连续保护膜的形成有关.

Abstract: Ni₃Al-based composite coatings containing different mass-fractions of Ag solid lubricant were prepared on the 310S austenitic stainless steel by laser cladding technology, and the effects of Agmass-fraction(5%, 10%, 15%) on the phase composition, microhardness, tribological properties and worn surface phase composition of the coatings were investigated. The results showed that the microhardness of the composite coatings decrease with the increasing of Ag content due to its soft nature, and the coating still has relatively high microhardness when the Ag content reach 10%, which is about 198.37 HV. The introduction of 10% Ag into the Ni₃Al coatingreduce the friction coefficients of the coating from 0.69~0.55 to0.62~0.41 at 25~800 ℃, and the wear ratesof the coating decrease from (2.27~1.60)×10^－5 mm³/(N·m)to (1.28~0.44)×10^－5 mm³/(N·m)at 400~800 ℃. The enhancement of the anti-friction ability of the composite coating is related to the synergistic lubrication of the diffusive migration of soft metal Ag within 25~400 ℃ and the oxidation products of Ni₃Al and Ag within 400~800 ℃; while the improvement of the wear resistance of the coating is associated with its higher mechanical strength and the formation of a continuous protective film on the worn surface.
