Abstract
To enhance the wear resistance of AlSi30Cu5 coating even further, TiC-reinforced AlSi30Cu5 (TiC/AlSi30Cu5) coatings were prepared using TiH2-C-AlSi30Cu5 agglomerates by HVOF. The results confirmed that the phases composition of TiC/AlSi30Cu5 coating included α-Al, β-Si, θ-Al2Cu, β-Ti, TiC, rutile TiO2 (R-TiO2), and anatase TiO2 (A-TiO2). The mechanical properties of TiC/AlSi30Cu5 coating, microhardness and fracture toughness, were greatly improved by 37.8 % and 5.5 times. The combination of high hardness, high fracture toughness and residual graphite significantly strengthened the wear resistance of TiC/AlSi30Cu5 coatings by 91.1 % and 54.1 % over the substrate and AlSi30Cu5 coating. Analysis of the worn morphologies and abrasive debris revealed that the wear mechanisms of TiC/AlSi30Cu5 coating were primarily abrasive wear, with contributions from oxidative wear and fatigue wear.
