In addition, the ratio between the surface scratch hardness h of coating 50 and its thermal coefficient λ are in 0.25 (mK) H/W~27 (m
K) between H/W, on the one hand, the ratio both avoided is too small, i.e. the surface scratch hardness h of coating 50 is too small or coating 50
Thermal coefficient λ it is excessive, cause coating 50 softer, not wear-resisting, influence coating 50 service life or increase by 50 cost of coating
Or the case where influencing noise reduction effect, occurs；On the other hand, the ratio for avoiding the two is excessive, i.e. the surface scratch of coating 50 is hard
