Tribological Properties of Self-repair Sn-based Semi-liquid Grease for Steel-copper Tribo-pair
钢-铜摩擦副自修复锡基半流体脂的摩擦磨损性能研究

Sn powder of micronmeter in particle size,Li grease and VG32 oil were mixed so that a Sn-based semiliquid grease were prepared and used as a new kind of lubricant for steel-copper tribo-pair.Friction tests were carried out on a modified model MS-800 4-ball tester.Chemical composition and surface elemental distribution on pure-copper samples were analyzed with Auger Electron Spectrum(AES).Thickness and its surface morphology of self-repair coatings formed on pure-copper samples by Sn grease were analyzed by ...
