摘要: 对钼基伪合金涂层的设计及摩擦、磨损性能进行了试验研究,并进行了微观组织结构分析。结果表明:将钼粉、自熔性合金粉及氧化铝陶瓷粉进行混合,利用等离子弧喷涂工艺,可以获得耐磨、减摩钼基伪合金涂层,并且各相分布均匀,结合良好,是软硬相间的多孔的典型耐磨表面强化模型,为开发适用于边界润滑条件下表面功能性涂层提供了依据。

Abstract: Experimental study on molybdenum base pseudo-alloy coating and its friction and wear performance is carried out. Through the analysis of microstructure of the coating, the result showed that blending the molybdenum powders, self melting powders and alumina powelers followed by plasma-spraying the wear-resisting and anti-friction molybdenum base pseudo-alloy coating could be formed. Phases of it distributed homogeneously and bonded well, which was a typically strengthened model-Multicelluler wear-resisting surface between soft phases and hard phases. This research may contribute to provide bases to develop face functional coating working under boundary lubrication conditions.
