Characteristics and application:
Mo + 30% NiCrBSi composite material, by using plasma spraying preparation wear-resisting coating. The organizational structure of the coating ,is uniformity in the Mo flat deformation of particles inlaid the NiCrBSi deformation particles. The coating has two kinds of material properties, Its advantages are as follows. 1. Coating of Mo-based, have a good anti-scuffing, and can withstand the instantaneous friction and high temperature. 2. NiCrBSi alloy hardness of the coating is high, Excellent abrasive wear resistance, thus improving the wear resistance of the coating under high loading. 3. The inherent porosity (8-15%) of the coating has the effect of oil storage. When in a critical state of lubrication, the lubricating oil in the pores due to friction and high temperature expansion, and spills along the gap, and thus play a good lubrication regulatory role. Save oil also played an endothermic effect, to transfer heat to the cylinder wall.
Due to the above advantages, coating raise the high loading abrasion resistance performance in the high loading and kept resistance to wear in the low loading ,it is the most ideal piston ring coating.
Mainly used for piston ring, automobile synchronous ring, fork, etc
