Abstract :
A combined dc magnetron sputtering and multi-arc deposition system was used to grow CNX/TiN composite films on a high-speed-steel (HSS) substrate. The thickness of these films is about 3 μm, the hardness of the coating exceeds 50 GPa. The sliding friction properties were studied by ball-on-disc tests under different loads and speeds. The wear mode of the films was observed and analyzed. There exist spallation, abrasion and micro-ploughing wear modes under different loads. The critical load value was theoretically determined and tested to be 55 N. The results show that the alternating films have good wear resistance under heavy load and high speed.
