In this paper, the AlCrTiN coatings deposited by the cathodic arc method using a plasma filtration system have
been studied to determine the effect of the use of this technology on the structural, mechanical, and tribological
properties of these coatings. The results of the studies have revealed that using a plasma filtering system in
the cathodic arc evaporation process has a significant influence on smoothness, hardness, Young's modulus,
and plasticity of the coatings. Compared to the AlTiCrN coatings that have been deposited by the standard arc
cathodic process, the coatings produced by filtered method have very smooth surfaces as well as lowered values
of hardness, less Young's modulus, and a lower plasticity index H3/E2. Presented properties make coatings
of this type able to dissipate elastic energy that is accumulated in them during the abrasion process by plastic
deformations, which in turn, results in the reduction of the tendency to create damage in the coatings and cause
a limitation of wear rate. Improved tribological properties of the AlTiCrN coatings produced by filtered cathodic
arc technology indicate a very promising solution for a wide range of tribological applications.
