Summary: The effect of nano-WC particles on the wear resistance and impact resistance of Ni-based coatings was studied. Nano-WC can refine the microstructure, reduce wear rate, and improve impact toughness. It hinders crack propagation and reduces dislocation slip. Therefore, nano-WC can significantly improve the wear resistance and impact resistance of the coatings.

Summary: This paper investigates the interface microstructure and wear resistance of WC-iron matrix composites prepared by adding different alloying elements Ni, Mo, and Fe using the casting method. The results show that the composites produced a metallurgical bonding interface transition layer under different alloy elements, mainly consisting of Fe3W3C and M7C3 carbides. The composite with Ni addition exhibits the smallest wear weight loss and the best wear resistance, which is mainly attributed to the hardness of different zones of the composite and the interface transition layer formed after adding alloy elements.

Summary: Metal matrix composites reinforced with WC particles and Co or Ni matrices are known for their unique combination of hardness, toughness, and superior wear performance. This study focused on Ni-WCNi composite coatings and found that coatings with higher WC fill ratios displayed better wear resistance due to the uniform distribution of WC particles and shorter mean free path reducing adhesive wear. However, at higher loads, subsurface crack propagation at WC particle interfaces led to a reduction in the protective role of mechanically mixed layers. Scratch tests were used to qualitatively compare coating cohesion strengths and correlate them to wear properties.

Summary: Ni/WC composite coatings were prepared on 304 steel surface by high-speed laser cladding. The microstructure and phase composition of the coatings were analyzed, and the hardness and wear resistance were tested. The results showed that the coating had good surface formation without defects, and WC particles hindered dendrite growth and refined the dendrite structure. The main phase of the coating was Ni3Fe, and WC decomposition produced strengthening effects. The hardness and wear resistance of the coating improved with increased WC content.

Summary: This study investigates the effect of nano-La2O3 doping on the tribological behavior of laser cladded WC-12Co coating on 65Mn steel under water lubrication. The microstructure, hardness, and wear resistance of the composite coatings prepared with the optimal doping amount of La2O3 were evaluated. The results show that nano-La2O3 doping significantly improves the hardness and wear resistance of the coating, and the tribological mechanism involves the direct contact of the friction surface, synergistic lubrication of ZrO2, and mixed lubrication.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
