摘要
利用低温(<300℃)等离子化学气相沉积技术,在活塞环表面生成一层双向扩散的微晶体与网状结构并存的氮化硼-氮化硅金属复合陶瓷层,提高了环的表面硬度、耐磨性,降低了摩擦系数,常温下导热系数可提高42%,并随温度升高呈指数规律上升。从而降低环的工作温度,减少变形,提高气密性,改善发动机整体性能。
Cryogenic plasma chemical gas sedimentary techniques is used to generate a layer of boron nitride-siliconnitride metal compound ceramic coating, which contains both two-way diffusing micro crystal and network configuration.By this technology, apparent consistency and abrasion resistance is improved and friction coefficient is reduced. Coefficientof thermal conductivity in ordinary temperature can be raised 42% and the exponent ascend regularly with the rise oftemperature. Therefore, the working temperature is lowered , the chance of deformation is reduced, airtightness is enhancedand engines global performance is improved.(1.
