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..
