hexagonal boron nitride (h-BN) powders in preform and subsequent chemical vapor infiltration (CVI) process. Friction and wear properties of C/C-BN were investigated on an MM-1000 testing machine. The morphologies of wear surfaces were observed by optical microscope. The morphologies of wear debris and the microstructures of samples were analyzed by scanning electron microscope. The results show......

to increase the wear resistance. The phase and microstructure of the coatings were analyzed by X-ray diffractometry and transmission electron microscopy. The wear properties of the coatings were also investigated by means of sliding wear test. The results show that the coating consists of amorphous phase in majority and nanocrystalline phase in minority. The amorphous coatings can be obtained while......
