中文摘要：

通过高能球磨与粉末冶金技术制备高强度自润滑PM304涂层，PM304涂层相对密度达到93％、抗拉伸强度达47MPa，相比等离子喷涂制备的PS304涂层，相对密度与抗拉伸强度明显提高。并且，涂层中的自润滑成分尺寸细小且分布均匀，其中Cr2O3粒子尺寸为100nm左右，BaF2／CaF2粒子为1μm左右。

英文摘要：

Self-lubricating PM304 composite with high strength has been prepared by high-energy ball milling and powder metallurgy. The relative density achieved 93%, and the tensile strength was about 47 MPa, which is much higher than those of PS304 made by plasma sputtering. Besides, the self-lubricating particles in composite present a very fine and uniform distribution. The particle size of Cr2O3 is about 100 nm, and BaF2/CaF2 less than 1 μm.
