摘要
采用自行改造的多弧—磁控溅射离子镀膜机在铸铁活塞环表面进行Ti TiN多层镀研究 ,并运用实验手段对膜层的组织、相结构、显微硬度、膜—基复合强度、内应力 ,以及活塞环—缸套摩擦副的磨损量进行分析 ,结果表明采用多弧—磁控溅射复合工艺在铸铁活塞环表面沉积膜厚大于4μm的Ti TiN多层复合镀层是可行的 ,该工艺能明显改善活塞环—缸套摩擦副的耐磨性。
The Ti\|TiN multi\|layer compound coating on cast iron piston ring by authors\|improved multi\|arc and magnetron sputtering ion compound plating device has been investagated by measuring the total thickness,fractography morphology,phases,micro\|vickers hardness,compound strength of coating and sabstrate, internal stress,were resistance of respective coatings. The experimental results show that Ti\|TiN multi\|layer compound coating thicker than 4μm can be obtained on cast iron piston ring, and the wear resistant properties of cast iron piston ring\|cylinder pair of internal\|combustion engine can be appreciably improved by this technique.
