摘要: Abstract Four types of different hard transition metal nitrides (TMN:ZrN, CrN, WN and TiN) coatings were deposited on Si (100) 316LN stainless steel substrates using DC magnetron sputtering. A comprehensive study microstructure substrate dependent tribo-mechanical properties TMN was carried out. Higher hardness (H) elastic modulus ( E ) obtained for H =40 GPa =440 GPa) TiN =30 GPa =399 GPa) coatings. This is related to the formation (111) preferred orientations in coatings, respectively. However, less ZrN CrN where (200) orientation preferred. Remarkably, low friction coefficient (0.06–0.57) higher wear resistance are directly associated with plastic deformation 3 /E 2 presence intrinsic compressive stress.
