“…WC-CoCr metal-ceramic coatings, produced by using HVOF, have been extensively studied for their exceptional mechanical properties in enhancing cavitation resistance on substrate surfaces [4][5][6]. Current research focuses mainly on the wear resistance of WC-based coatings [7][8][9], and limited studies investigate the effect of heat treatment temperature on cavitation resistance. This work examined the influence of heat treatment temperature on the microstructure, porosity, microhardness, and fracture toughness of multi-scale WC-10Co4Cr coatings.…”

The multi-dimensional WC-10Co4Cr coating was prepared on 316 stainless steel by using HVOF spraying, and the impact of heat treatment temperature on the microstructure, cavitation resistance, and mechanical properties of the multi-dimensional WC-10Co4Cr coating was studied. Heat treatment at higher temperatures leads to lower porosity and upper hardness of the coating. Meanwhile, oxidation products such as CoWO4 and Cr2O3 were produced at 500°C. The coating has the best anti-cavitation performance after heat treatment at 300°C.

“…However, low hardness and poor wear resistance make it prone to failure in abrasive environments, thereby reducing its service life [2]. Therefore, it is necessary to take some surface cladding techniques to improve the performance of the copper material surface [3][4][5].…”

The in-situ synthesis of TiC reinforced Ni-based coatings were prepared on copper substrates by using precursor materials (TiFe and Cr3C2) by plasma cladding. The coating consisted mainly of γ-(Cu, Fe, Ni), TiC, CrB and Cr23C6. The generated TiC particles tend to float up to the upper part of the coating to aggregate and grow, so the TiC concentration in the upper part is larger. The hardness of the TiC composite coating is distributed in a gradient, and the average hardness is 700 HV, which is 13.0 times that of the copper matrix. The wear mechanism of TiC composite coating is abrasive wear, and the wear resistance is 13.0 times that of the copper substrate.
