Abstract Vitreous enamel is a very interesting coating for both aesthetical and technical purposes. The deposition of enamel coatings can be exploited on different materials, such as steel, cast iron and aluminium alloys, and it allows to greatly improve their mechanical, chemical, corrosion and thermal protection properties. Despite their high hardness, enamel coatings show limited abrasion resistance, mainly due to their vitreous nature and brittle behaviour. Recently, many studies tried to im...

Abstract This manuscript presents the nature of interaction of energetic plasmoids, generated in the Gas Injection Magnetron Sputtering (GIMS) technique, with the surface of substrate or the coating–substrate system. We expected that the plasma generated by a dynamic injection of gas (GIMS) is better ionized than the plasma generated in stationary pressure in its standard range for magnetron sputtering. The GIMS technique operates under conditions that may favor the plasma species to retain thei...

Abstract This work reports the preparation of oxide-based ceramic composite coatings as potential thermal barrier coatings (TBC) on ferrous alloys, targeting automotive applications. The coatings are shown to have excellent adhesion due to fabrication by plasma electrolytic aluminating (PEA), an anodic plasma electrolytic deposition process. The PEA process was conducted in an aluminate-containing aqueous electrolyte under a high voltage. The coating has superior adhesion (>60 MPa) and low therm...

Abstract Shot peening is a mechanical surface treatment widely utilized to enhance the fatigue strength of gears by surface work hardening and inducing compressive residual stresses while also altering the surface roughness. This study is aimed at developing a detailed numerical model of dual shot peening on case hardened gears by considering the variation of material properties through the thickness. Two different approaches were implemented to estimate the gradient material properties of case-...

Abstract The effects of shot peening (SP), ultrasonic surface rolling (USR), and laser shock peening (LSP) processes on the surface integrity of TC17 alloys, including the surface topography, in-depth residual stress and microhardness distributions, and microstructure, are investigated and compared. The results show that the lowest surface roughness values of 0.04–0.12 μm and a smooth surface topography are achieved from the USR process, while those after the SP and LSP processes are 0.50–1.07 μ...

Abstract A promising new bond coat using CuAlNiCrFe high-entropy alloy was proposed in this paper. The difference in pre-oxidation conditions between the traditional thermal-sprayed MCrAlY bond coat and CuAlNiCrFe high-entropy alloy bond coat deposited using high-speed laser cladding was investigated. The result confirmed that the CuAlNiCrFe high-entropy alloy bond coat deposited using high-speed laser cladding can complete the pre-oxidation faster and form a continuous α-Al2O3 thermally grown o...

Abstract This research work presents the deposition of titanium oxide (TiO2) reinforced hydroxyapatite (HA) on Ti-35Nb-7Ta-5Zr alloy by plasma spray deposition technique for Hip-stem application. The effect of TiO2 reinforcement (15 and 30 wt%) in HA has been studied on coatings morphology, microstructure, mechanical properties, corrosion resistance, and in-vitro bioactivity was investigated. The microstructure, elemental composition, and phase composition were characterized by FE-SEM, EDS, and ...
