Abstract
Stainless steel is a low-cost and broadly utilized material in many industrial and biomedical applications. However, its meager wear characteristics lead to substandard tribo-mechanical properties which decline their usage in many probable applications. Various surface modification methods such as electrochemical deposition, physical vapor deposition (PVD), and chemical vapor deposition have been conducted to deposit ZrN, TiN, TiC and TiN/ZrN multilayers on the surface of stainless steel to develop their surface properties. Depositing of thin films by PVD has been revealed across the broad used in abundant industrial applications. Pulsing the magnetron plasma discharge in the intermediate frequency ranged from 20 to 350 kHz recovers the central problem accompanied with the continuous dc reactive sputtering; explicitly the existence of arc at the target. It has been publicized that, pulsing the magnetron discharge will result in increasing the energy of plasma species and ion fluxes that supplied to the substrate compared with continuous dc discharges. Supplementary; the pulsed magnetron sputtering (PMS) process offers profits in depositing a wide range of materials. Titanium-based multi-component coatings demonstrated essentially improved tribo-mechanical properties compared to TiN coatings. Zr.
