Adhesion, structure, and mechanical properties of Cr HiPIMS and cathodic arc deposited coatings on SiC

Development of Standardized Property Requirements, Measurement Methods, and Reporting Guidance for Coatings

“…Since a large amount of shear forces can be imparted into the coating, scratch tests do add an additional testing mode as compared to an adhesion test which isolates an orthogonal force. It is not surprising that scratch testing of initial pure ceramic and multilayer ceramic/metallic coatings provided more standard and repeatable coating failures than that of pure metallic coating in Figure 12 [45]. Testing on ductile Cr coatings have shown that material plastically deforms but does not delaminate, with the indenter effectively spreading the coating along the surface of the sample.…”

“…The creation of cracks is more useful in studying the effectiveness of the coating at maintaining hermeticity during substrate cracking. Several tests where cracks were initiated in the substrate have been conducted [45].…”

Microstructure and Antimicrobial Properties of Zr-Cu-Ti Thin-Film Metallic Glass Deposited Using High-Power Impulse Magnetron Sputtering

“…High-power impulse magnetron sputtering (HiPIMS) is widely used to produce hard coatings, due to the fact that the ionization rate is equivalent to that of a cathodic arc [ 18 , 19 ]. This approach has proven highly effective in producing coatings with a smooth surface [ 20 , 21 ] with a density higher than that of DC magnetron sputtering (DCMS) [ 22 ]. Nonetheless, there has been relatively little research on the use of HiPIMS deposition for TFMGs.…”
