The aim of this paper was to study the effectiveness of N2/Ar gas ratio on the mechanical and tribological properties of Ti-Zr-N films coated on (AISI 304 stainless steel) substrate. The thin films were produced at 150 W pulsed magnetron sputtering (PMS) technique operated for 90 min. The structure and tribo-mechanical properties of the Ti-Zr-N coatings were investigated at different ... إقراء المزيد
