高能球磨-粉末冶金法制备硫化亚铁/铁基轴承材料的摩擦学性能
|
摘要
以Fe、C和FeS为原料,采用高能球磨工艺和粉末冶金法制备了FeS/铁基轴承材料,研究了材料的微观结构,并考察了其摩擦磨损性能。结果表明:高能球磨工艺改善了FeS颗粒的分布均匀性及其与基体的界面结合,材料力学性能高于未球磨材料;FeS属固体润滑剂且具有良好的储油特性,油润滑条件下FeS向摩擦表面转移易形成液-固润滑膜,起到了良好的减摩抗黏着作用,FeS质量分数为8%的球磨铁基轴承材料具有较好的减摩耐磨特性和较高的承载能力。
With Fe, C and FeS as raw materials, FeS/iron-based bearing materials were prepared by high energy ball milling technology and powder metallurgy. The microstructure of the materials was studied and the friction and wear properties of the materials were investigated. The results show that the high energy ball milling processes may improve the distribution uniformity of FeS particles and the interface bonding with the matrix. The mechanics properties of the materials are higher than those of the non ball milling materials. The FeS belongs to the solid lubricant and has good oil storage characteristics. Under oil lubrication, the transfer of FeS to the friction surface is easy to form a liquid solid lubricating film, which plays a good antifriction and viscosity reduction. The 8% FeS ball milling iron-based bearing materials have better friction reducing wear resistance and higher load capacity.
