Tribological Behaviors of Titanium Nitride- and Chromium-Nitride-Based Physical Vapor Deposition Coating SystemsSource: Journal of Engineering for Gas Turbines and Power:;2012:;volume( 134 ):;issue: 011::page 112504DOI: 10.1115/1.4007168Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study investigates the effects of the deposition process and coating composition on microstructural and tribological properties of TiN- and CrN-based coating systems. Coatings were produced using various PVD-based processes—electron beam (EB), cathodic arc (CA), and plasma enhanced magnetron sputtering (PEMS). All coated samples were evaluated for their composition, microstructure, and surface morphology. Coating mechanical properties such as hardness, Young’s modulus, and coefficient of friction were also studied and related to their microstructures, wear, and erosion resistances. It was found that hardness (H), Young’s modulus (E), and coefficient of friction had impact on both wear and erosion rates. In particular, the H3 /E2 ratio was inversely proportional to the specific wear rate. For erosion behavior, higher H3 /E2 ratios relate to lower erosion rates at low impingement angles, whereas higher H3 /E2 ratios relate to higher erosion rates at high impingement angles.
