چکیده
Hard and wear-resistant coatings created utilizing physical vapor deposition (PVD) techniques are extensively used in extreme tribological applications. The friction wear behavior of vary significantly with temperature, indicating that advanced coating concepts essential for prolonged load-bearing Many have recently been explored this area, including multicomponent, multilayer, gradient coatings; high entropy alloy (HEA) nitride; functionally modified coatings. In review, we highlighted the most significant findings from ongoing research to comprehend crucial properties design aspects. To obtain enhanced properties, microstructure, composition, residual stress, hardness, HT oxidation resistance tuned through doping or addition appropriate materials at an optimized level into primary Such improvements achieved by optimizing PVD process parameters such as input power, partial pressure, reactive gas flow rates, substrate bias, temperature. incorporation ideal amounts Si, Cr, Mo, W, Ag, Cu ternary quaternary coatings, well unique multilayer designs, considerably increases performance Recent discoveries show not only mechanical hardness fracture toughness govern resistance, but also plays a role lubrication failure tribo-induced metal oxides and/or Magnéli phases concentrated tribolayer key governing factors temperatures. This review includes detailed insights advancements various mechanisms associated temperature changes.

Properties of PVD hard coatings
Last 2 to 3 decades application of PVD (physical vapour deposition) hard coatings exponentially grows. However, the use of hard, thin films in the field of machine elements is the exception rather than the rule. The main problem lies in the relatively high contact pressure and the very complex loading of machine components, which demand a hard resistance surface and a tough core. In seminar it ...

In the aluminum die casting process, erosion, corrosion, soldering, and die sticking have a significant influence on tool life and product quality. A number of coatings such as TiN, CrN, and (Cr,Al)N deposited by physical vapor deposition (PVD) have been employed to act as protective coatings due to their high hardness and chemical stability. In this study, the wear performance of two nanocompo...
متن کاملEffect of Annealing Temperature on the Water Contact Angle of PVD Hard Coatings
Various PVD (physical vapor deposition) hard coatings including nitrides and metal-doped diamond-like carbons (Me-DLC) were applied in plastic injection and die-casting molds to improve wear resistance and reduce sticking. In this study, nitrides hcp-AlN (hexagonal close-packed AlN), Cr₂N, (CrAl)₂N) and Me-DLC (Si-DLC and Cr-DLC) coatings were prepared using a closed field unbalanced magnetron ...
