Some Applications of Cathodic Arc Coatings

Adhesion enhancement of DLC hard coatings by HiPIMS metal ion etching pretreatment

“…The deposition of DLC coatings on engineering components is a standard activity in key industrial sectors including automotive [5,6], micromachining [7], aeronautic [8] or biomedical [9]. The exceptional DLC tribomechanical properties are achieved by means of highly energetic deposition techniques such as cathodic arc evaporation (CAE), pulsed laser deposition (PLD), ion beam deposition, plasma immersion ion deposition, and magnetron sputtering (MS) [10][11][12]. As a result, typical DLC coatings are grown with high levels of compressive residual stresses, which limit the coating thickness, and usually lead to delamination failure [13,14].…”

Microstructure and load bearing capacity of TiN/NbN superlattice coatings deposited on medical grade CoCrMo alloy by HIPIMS

“…The surface morphology of the coatings further confirmed that the column tops are indeed smooth, which contributes to the small value for the surface roughness of R a = 0.06 μm. In comparison the surface roughness of state-of-the-art arc deposited monolithically grown TiNbN is at least one order of magnitude higher due to the large amount of droplet phase (Anders, 2008) landing on the surface during coating growth and therefore producing great deal of surface defects, which are detrimental for the corrosion performance of the coatings for implant applications (Hovsepian et al, 2016).…”
