对于内燃机活塞环和汽缸的表面处理层,除要求其具有良好的耐磨性外,还要求具备能承受火焰燃烧而不剥落的能力。日本的铃木祥司和矢口勋发明一种复合镀层,能满足以上要求。这种复合镀层是将一种金属氧化物、金属炭化物以一定比例投放入镀液中,电镀而成。金属氧化物、金属碳化物的用量控制是极重要的,过低过高,不仅影响产品价格,而且影响到镀层性能。 For engine piston ring and cylinder surface treatment layers, in addition to requiring good abrasion resistance, they also require the ability to withstand flame burning without spalling. Japan Suzuki Cheung Division and Yaguchi Hoon invented a composite coating, to meet the above requirements. This composite coating is a metal oxide, metal carbide in a certain proportion into the bath, electroplating. Metal oxide, metal carbide dosage control is extremely important, too low, not only affect product prices, but also affect the coating performance.
