The scratch depth of BCN films were mainly depended on the component of bonding structures in the films, but the effect of bonding structures on the friction coefficient was not obvious.
BCN薄膜的划痕深度与薄膜的结构密切相关，而摩擦系数受薄膜结构的影响不明显；

The present case deals with testing of brake bodies, consisting of a steel base plate, a welded-on grid mat as bonding agent and the sinter-fused braking substance (friction lining).
