“…Franco et al [27,28] investigated the influence of nickel composite coatings on silicon carbide particles reinforced onto aluminum alloy (LM24). They found that the microcracks in the matrix were continued to propagate until it is interrupted by the coated reinforced particle.…”

This paper mainly focuses on parametric optimization of squeeze cast hybrid (LM24-SiC p-coconut shell ash) composite through Taguchi method and genetic algorithm. The composite samples have been cast through squeeze casting for each experimental trial based on L 9 (3) 4 orthogonal array. From analysis of variance, it has been found that reinforcement and squeeze pressure were the casting parameters making significant improvement in the impact strength. A mathematical model representing the process was developed using nonlinear regression analysis. The optimum casting conditions were obtained through Taguchi method and genetic algorithm and checked through the confirmation experiments. In this study, it was confirmed that the castings obtained for the optimum squeeze casting conditions exhibited nearly 20% improvement in impact strength compared to the gravity die casting condition.

“…The ideal crystalline grain size is obtained from thermal processing at 400 °C. In the present case, the embedding particles promote elimination and stoppage of microcracks [19]. Further, the synergistic effect of heat treatment and the reinforcing particles shows positive influence in crack elimination and stoppage.…”

“…Among pre-heat treated coatings, the trend follows in which particles free coating has the lowest microhardness and the maximum microhardness value is reached with a specific content of reinforcing particles beyond which no significant change is observed [16]. No direct measurements were carried out on adhesion and toughness of the coatings, but an indirect investigation has been reported [19].…”

“…After reinforcing, the combined effect of matrix and the particles at the testing temperature may have effectively reduced the amount of microcracks [19]. The plastic deformation on the wear surface is roughly via a grinding action by material mixture of varied sizes under the action of the shear force during sliding.…”

The investigation is focused on the wear behaviour at elevated test temperature of composite Ni-P/SiC deposit, with varying concentration of the reinforcing SiC particles. The phase evolution measured by X-ray diffraction suggests slight crystallisation during wear testing at 200 °C. In coating without reinforcing particles, adhesive wear is accompanied by microcracks. The thermal heat generated and the cyclic loading could have induced subsurface microcracks. Owing to the effective matrix-ceramics system in composite coatings, fine grooves, abrasive polishing and uniform wearing are observed. Reinforcing particles in the matrix hinder microcrack formation and significantly reduce the wear rate. Triboxidation is confirmed from energy dispersive X-ray spectrometry.
