A series of TiN films with different thickness were prepared by a mid-frequency magnetron sputtering(MFMS) system.The nanohardness,adhesion strength to substrate,friction coefficients and tribological properties of the TiN thin films were studied.The morphology results showed that the obtained TiN films have smooth surfaces and few defects exsisted,but as the thickness of the film increasing,the films may tear off from the substrate due to excessive inner stress.Although their thicknesses increase with increasing deposition times the nanohardnesses of the films kept constant(about 21 GPa).The critical loads measured by scratch test increased as the thickness of the film increasing,but when the thickness is too high,the critical load will drop down due to its high inner stress,which means that the adhesions of the films to substrates can be enhanced with appropriate increase in film thickness.The friction coefficients measured in tribological experiment were different when the applied loads were different;in this study,with loads of 20 g,50 g and 100 g,the measured friction coefficients,which may match those of TiN films,a special transition layer between films and substrates,and the stainless steel substrate,are 0.05,0.41,and 0.69,respectively.The combined tribological properties of the coated materials could be improved with a proper thickness of films.
