内燃机活塞组耐磨涂层材料的试验研究

A Test Study of a Coating Material of Wear-resistantin Piston Groups of Diesel

应用配方均匀设计方法，对中低速内燃机活塞组摩擦副的耐磨、耐蚀、耐高温涂层材料进行了定量研究．试验点在试验范围内分布均匀，试验次数少，缩短了试验周期．经对喷涂层的热稳定性、摩擦磨损特性的研究，提出了涂层材料各组分的优化组合，为定量研究开发新的涂层材料提供了方法。

in this paper, a coating material of wear-resistant, bearing corrosion and enduring higher temperature in middle and low speed diesel is studied quantificationally with a uniform prescription design method,which reduced the test period as the test points distribute uniformly. An optimized combination is put forwardof each part in the coating by studying its heat stability and wear property, and a method to develop a new coating material is supplied.
