Abstract
Ternary TiAlN coatings were deposited on brass substrates by magnetron sputtering method. This paper is focused to study the effect of nitrogen:argon (N2:Ar) gas ratio on tribological properties of TiAlN coatings. TiAlN coatings displayed (1 0 1) peak at N2:Ar gas ratio value of 08:02. The evolution of single (1 0 3) peak for TiAlN coating was observed when the N2:Ar gas ratio values were 08:00, 08:02, 08:5.2 and 08:12. The characterization of TiAlN coatings was studied using scanning electron microscope (SEM). The evolution of well-crystalline structure of TiAlN coatings is observed with increase in N2:Ar gas ratio from 08:00 to 08:12. The tribological properties of TiAlN coatings were tested by pin on disc tribometer at different values of load and sliding distance.
