Tribological Behaviors of Titanium Nitride- and Chromium-Nitride-Based Physical Vapor Deposition Coating Systems

Abstract

This sttidy 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 H^IE^ ratio was inversely proportional to the specific wear rate. For erosion behavior, higher H^IE^ ratios relate to lower erosion rates at low impingement angles, whereas higher H^IE^ ratios relate to higher erosion rates at high impingement angles.

“…PVD technology requires the source material in solid or liquid form to be gasified into gas atoms or molecules under vacuum by physical methods, and then the gaseous material atoms or molecules are controlled to deposit on the substrate surface to obtain the material film. PVD technology is a common and widely used surface treatment technology 68,69 and can prepare very thin (10 −7 –10 −4 m) layers, 70 which plays an extensive and momentous role in the preparation of 2D materials. 71 Several special PVD technologies have emerged, such as vacuum evaporation coating, molecular beam epitaxy (MBE), and pulsed laser deposition (PLD).…”

Structure Optimization and Failure Mechanism of Metal Nitride Coatings for Enhancing the Sand Erosion Resistance of Aluminum Alloys

“…Physical vapor deposition (PVD) of metal nitride coatings, which exhibit high hardness and excellent wear resistance, holds promise in enhancing the erosion resistance of aluminum alloys against sand [10][11][12][13]. The oxidizable nature of aluminum hinders the proper interfacial bonding between aluminum and nitride coatings [7,[14][15][16][17]. Youming Liu et al successfully improved the bonding strength of a TiN/Al system by a factor of six with the ion source injection (MEVVA) of Ti metal particles and Ti intermediate layer pretreatment [18][19][20][21].…”

Solid particle erosion mechanisms of protective coatings for aerospace applications

“…However, they are difficult to implement in practice since they need to be deposited at temperatures that exceed the permissible limits of the metallic components. For that reason, the most frequently used coatings for SPE protection are TiN-based in monolithic [85,87,89,91,92] or multilayer [90,105,106] forms, which can be deposited on technologically relevant substrates.…”
