摘要: 通过溶胶-凝胶法在45#钢基体上制备了厚约500μm的FeS固体润滑涂层.摩擦 磨损试验结果表明,FeS固体润滑涂层具有良好的减摩效果和耐磨性能.由于涂层较厚,摩擦 行为只发生在涂层内部,很好地保护了基体不被磨损.利用XRD检验了涂层的相结构,通过 SEM+EDX观察分析了涂层在表面的磨痕形貌及能谱分布.

Abstract: The FeS solid lubrication coating with 500μm thick was prepared by a sol-gel method on the 1045 steel. XRD was used to detect the coating phase structures and SEM equipped with EDX was utilized to observe and analyze the morphologies and energy spectrum of the coating s surface and worn scars. The friction and wear tests show that the coating possesses good properties of anti-friction and wear-resistance. Because the thickness of the coating is much thick, the friction behavior only happens within the coating. So the steel substrate is kept away from wear.

Key words: sol-gel, iron sulfide, coating, solid lubrication
