Abstract

AlTiN nano structure multilayer coating were depo sit adopting alternating Arc source technology, two layers Ti+TiN/AlTiN was deposit alternately. During thick coating experiments and cutting experiments show the comparison with in AlTiN monolayer gradient coating & nanostructure multilayer coatings. The AlTiN nano structure multilayer coatings show better mechanical properties such as adhesion of coating, wear resistance & etc. Experiments show that AlTiN nanostr ucture multilayer coatings show more excellent wear resistance impact than AlTiN monolayer gradient coating. And AlTiN nano structure multilayer films relieve the stress concentration inside the coatings, so more layer of thick coating can be deposited if needing; the structure of nano structure multilayer improves adhesion of coating, and showing better mechanical performance..
