Two types of hard coatings Cr3C2-25NiCr and 35WC-Co/65NiCrBSi were sprayed on an SS-347 steel substrate. The erosion tests were done using high-temperature jet erosion set up to study the effect of velocity, temperature and impact angles on the coatings produced. The surface morphology of the samples was characterized using 3D laser confocal microscopy, light microscopy, scanning electron microscopy with EDAX and X-ray diffraction. Microhardness, porosity level and roughness parameters were evaluated to infer a probable mechanism of material removal. The Cr3C2-25NiCr coating exhibited ∼3.3 times higher erosion resistance than 35WC-Co/65NiCrBSi coating at 90° and 30° impact angles. SEM and 3D laser confocal images on the eroded surface of the coatings reveal the combination of ductile and brittle fracture of coating.

In addition to grain refinement, decreased intermetallic phase (MgZn) was also observed after FSP. Increased micro-hardness was observed for the processed ZE41 Mg alloy compared to the unprocessed base alloy. X-ray diffraction (XRD) studies demonstrated the texture characteristics in FSPed ZE41. Reciprocating wear studies conducted at three different temperatures, i.e. room temperature, 125 °C, and 250 °C showed lower mass loss for the processed alloy compared to that of the base alloy, particularly at elevated temperatures. This behavior can be understood by considering the benefit gained from the smaller grains and decreased amount of intermetallic phase in the processed alloy, which reduced the abrasion wear. Hence, the present study suggests that the grain refinement and decreased MgZn phase significantly improve the temperature-dependent tribological characteristics of ZE41 Mg alloy.

The thickness and microhardness of the coatings were measured while the microstructure was analysed with the aid of OM, SEM and XRD techniques. The X-ray diffraction results revealed the presence of W2C phase in the as-sprayed coatings, and WO3 and CoWO4 phases after the heat treatments. No significant degradation of the microstructure was observed in coatings treated at 350°C compared with the as-sprayed coatings. Coatings treated at temperatures above 450°C, on the other hand, showed significant changes related to density, microstructure and surface hardness. The coatings treated at 350°C showed the best wear resistance, while the coatings treated at 550°C presented the worst performance due to microstructural defects related to oxidation processes.

For Al–Si/n-Al2O3 (advanced composite), the coefficient of friction (COF) decreased by 34.41% and the wear resistance enhanced by 43.75% compared with base matrix alloys under high temperature (HT) conditions. For Al–Si/n-Al2O3/GNP (hybrid composite), COF decreased by 61.41% and the wear resistance improved by 96.87% at HT compared with base matrixes (eutectic Al–Si alloy). This finding was attributed to enhanced lubrication through GNP, glazed layer, thin tribooxide film (TTL) and mechanical mixed layer (MML) present on wear scars. Melt wear caused by scuffing was the main wear mechanism for the base composition at 300 and 400°C, and adhesion abrasion, crack formation and delamination pits were the wear mechanisms observed for the advanced and hybrid composites at extreme temperature conditions. Highlights Al–Si/ n-Al2O3 and Al–Si/ n-Al2O3/GNP composites were fabricated through spark plasma sintering. The tribological performance of the fabricated composite samples was investigated under dry sliding at elevated operating temperatures (100–400°C). The coefficient of friction and wear resistance improved with an increase in the secondary GNP reinforcement. Transition in the wear regime occurred at approximately 0.8 of melting temperature. The self-lubrication mechanism of GNP was observed on the wear track, which significantly reduced scar surface roughness.

For this purpose, LM27/SiCp composites were manufactured by stir casting route with reinforcement of different amounts (3–12 wt.%) and different sizes (fine: 1–20 µm and coarse: 106–125 µm) of SiCp. A comprehensive characterization of the friction and wear mechanisms ranging from mild to severe wear for oxidative and delamination at a contact pressure of 0.125–0.624 MPa was discussed. Results indicate that the friction and wear behaviour is strongly influenced by the morphology and the nature of the oxide scale on the wear track. In-situ formation of oxide layers on the contact region of the specimen supports the self-lubrication which supports better wear performance of LM27/SiCp composites. However, these study portraits that composite with 12wt. % fine size SiCp exhibits better wear performance in comparison to the other developed composites.
