Summary: The purpose of this study was to investigate the effect of initial surface conditions, cold spray temperature, and coating material on the wear resistance of cold sprayed coatings on WE43 Mg substrate. It was found that the samples with the greatest wear resistance were those coated with Zn, Ni, and Al2O3 powder mixture on sandpapered surfaces at temperatures of 600℃, where deposition efficiency is maximum. Cold spray coatings enhanced the wear resistance of the WE43 Mg substrate.

Summary: In this study, conventional and nanostructured Al2O3 and Al2O3-Y2O3 coatings were produced using atmospheric plasma spraying. The coatings were characterized in terms of phase composition, microstructure and chemical composition. The effects of the coatings on microhardness, crack propagation resistance, bonding strength and wear resistance were evaluated. The results showed that the nanostructured coatings exhibited a bimodal microstructure and the addition of Y2O3 stabilized the desired alpha-Al2O3 phase. Composite coatings displayed higher bonding strength due to better adhesion, chemical bonding and melting and wetting. Nanostructured alumina coating had higher crack propagation resistance than conventional coating, while conventional coating showed higher wear resistance due to its higher adhesion strength, hardness and denser microstructure.

Summary: This study investigates the influence of different accelerating gas temperatures on the deposition performance of Ni-coated Al coatings by cold spraying. The results show that increasing the accelerating gas temperature enhances the embedding depth of Ni-coated Al particles into the Al substrate, but not on the Q235 steel substrate. Additionally, the morphology, phase composition, porosity, and thickness of the coatings are affected by the accelerating gas temperature.

Summary: By adding an appropriate amount of Al2O3 particles to the feedstock, the performance of cold sprayed metallic coatings on polymer substrates was effectively improved. The addition of Al2O3 influenced the microstructure, deposition efficiency, microhardness, electrical conductivity, and adhesion strength of the coatings. Furthermore, the molecular structure of the substrate was not affected by the impact of Al and Al2O3 particles during the cold spray process.

Summary: In this study, NiCoCrAlTaY coatings were prepared on cobalt-based superalloy substrates by high pressure cold spray technology, and their microstructure, mechanical property, and tribological behaviors were systematically studied before and after thermal exposure at 1050 degrees C. The results showed that NiCoCrAlTaY coatings with a very dense structure could be obtained by high-pressure cold spraying. The coating remained completely intact without any cracking and spalling after thermal exposure. However, the wear resistance of the coating significantly decreased after thermal exposure with a decrease in hardness and an increase in friction coefficient and volume wear rate.

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.
