LOW-POROSITY AND LOW-OXIDATION 316L STAINLESS-STEEL COATINGS DURING HVOF SPRAYING: NUMERICAL SIMULATION AND EXPERIMENT

Nianchu Wu, Rui Wang, Guotao Wang, Jiawei Cao

316L stainless-steel coatings with low porosity and low oxidation were successfully produced via High-Velocity Oxygen-Fuel (HVOF) spraying of 10–50 µm feedstock powder, combining numerical simulation and experimental validation. A gas-solid coupled multiphase flow model incorporating oxidation kinetics, employing Computational Fluid Dynamics (CFD), …

Enhancing tribological performance of 40Cr substrates through laser-cladded TiC-graded composite coatings

H. Liang, Jiawei Cao, Jinhua Chen, Guihua Hang

To address wear degradation in 40Cr alloy steel, this study employs laser additive manufacturing to fabricate TiC-reinforced coatings on 40Cr surfaces. Using 12CrNi2 alloy steel powder as the metal matrix, both gradient-reinforced and uniformly reinforced coatings are produced and systematically compared. The …

Tribological behavior of SiC/Si composites fabricated by vat photopolymerization

Chengli Li, Quhao Li, Shouren Wang, Jiawei Cao et autres

Silicon carbide/silicon (SiC/Si) composites are widely used in mechanical seals and water-lubricated bearings because of their outstanding mechanical, chemical and physical properties. Vat photopolymerization (VP) offers a new route for fabricating geometrically complex parts; nevertheless, the friction-and-wear mechanisms of SiC/Si composites produced …
