Comparative Analysis over Tribology Characterization of TiAlN and TiAlSiN PVD Coating on Plasma Nitride Alloy 20

The nickel–iron–chromium (alloy 20) is enriching by hybrid surface treatment through plasma nitride (PN) and physical vapor deposition (PVD) process. nitriding process takes 12 h at 500 °C. Potentiodynamic testing used to characterize the corrosion performance of treated material, followed morphological analysis exposed surface; XRD, EDX, SEM, hardness, tensile are investigate appropriate coating properties. Plasma PVD alloys exhibit perlite (γ + α′) phases martensite α) phases, respectively. microstructure ensures superior strength hardness. pin-on-disc tribometer test proposes analyze friction hard-faced behavior in dry sliding position. inclusion Si improves adherent oxide film, resulting a low wear rate TiAlSiN alloy 20. Due presence passive 20 exposes most region attain better resistance.Graphical Abstract
