Summary: In-situ TiC reinforced titanium matrix composites coating was prepared on the surface of Ti6Al4V using plasma transfer arc welding. The coating exhibited dense structure, no porosity, and good metallurgical bond with the substrate. Different phases formed in the coating contribute to its high microhardness and resistance to wear and corrosion.

Summary: In this study, industrial waste (LD sludge) was successfully used as a potential filler material in the PP matrix. The physical and mechanical properties of the PP-LD sludge composites were analyzed, and the effects of different parameters on the wear behavior were studied. Scanning electron microscopy was carried out for micro-examination of the surfaces and assessment of wear derbies.

Summary: This study aimed to investigate and optimize the effect of adding brown rice husk ash-derived alpha-silicon nitride and nickel-phosphorus reinforcements onto the surface of austenitic stainless steel via electroless coating. By using Taguchi experimental design and grey relational analysis, the composite coatings were prepared and optimized, resulting in improved tensile strength, surface hardness, and wear resistance. The addition of Si3N4 into the crystal lattice of iron offered higher hardness and wear resistance than Ni-P, leading to an overall improvement in coating performance.

Summary: The influence of different ceramic phases on the wear resistance and thermal conductivity of cold spray coatings was explored. The addition of Al2O3 or SiC improved the coating quality, and composite coatings with Al2O3 or SiC exhibited better wear resistance. The thermal conductivity of all coatings was lower than pure Cu coating, but significantly improved after annealing for composite coatings with Al2O3 or SiC.

Summary: In this study, Cr3C2-NiCr and WC-CoCr ceramic-metal coatings were produced using HVOF spraying. It was found that WC-CoCr coatings had higher microhardness and lower porosity compared to Cr3C2-NiCr coatings, resulting in lower cavitation erosion rates. The cavitation erosion mechanisms of the coatings varied at different flow velocities, with Cr3C2-NiCr coatings experiencing removal of chromium carbide particles, crater coalescence, and coating detachment, while WC-CoCr coatings were eroded at the binder phase, cavitation pits interlinked, and WC particles detached at different flow velocities.

Summary: The study revealed that coal particles with their acidic nature and irregular shape and size are able to generate more erosion wear, with the order of erosion wear generated by different erodents being coal > bottom ash > fly ash. Additionally, particle size has the highest impact on the erosion wear rate of SS-410.

Summary: The study focuses on the compatibility of intermediate layers for the plasma-sprayed porous YSZ abradable sealing coating (ASC) on SiCf/SiC ceramic matrix composites (CMC). Through isothermal exposure and thermal shock tests at 1200 degrees C, the YSZ topcoat experienced decomposition, formation of mud-cracks and thermally grown oxide, along with the reaction layer of Yb2Si2O7. The coated samples exhibited a bond strength of 5.47 +/- 0.85 MPa and showed excellent high temperature hardness stability with a minimal increase in Superficial Rockwell Hardness (HR15Y) after 1200 degrees C isothermal exposure. The abradability of the ASC was influenced by the hardness and thermal conductivity of the encountered balls.

Summary: In this paper, a micro-nano structural ceramic coating with good hydrophobicity and wear resistance was successfully prepared using the sol-gel method. The coating's surface morphology, hardness, roughness, wettability, and tribological properties were characterized. The results showed that the micro-nano structure coating has the lowest wear rate and smallest plastic deformation, indicating improved wear resistance.
