Summary: WC-Ni composite coating was prepared on a 65Mn steel substrate using vacuum and laser cladding. The coating's microstructure, elemental distribution, and phase composition were analyzed by SEM, EDS, and XRD. Wear and corrosion resistance of the coating were compared through wear and electrochemical tests. The results showed that vacuum and laser cladding significantly improved the substrate's wear and corrosion resistance. Vacuum cladding exhibited better wear resistance, while laser cladding exhibited better corrosion resistance. The average wear resistance of the coating was high, making vacuum cladding a preferred process. Laser cladding could enhance the coating's extended wear and corrosion resistance.

Summary: In this study, high entropy alloys (HEAs) coating was successfully used to enhance the wear and corrosion resistance of civil commercial engine blades. It was found that Ni1.5CrFeTi2B0.5Mox HEAs showed good bonding properties and the addition of Mo changed the coating structure, improving corrosion resistance. These findings suggest that HEA coatings can greatly improve the microhardness and wear resistance of the material, with Mo additions showing lower wear rates and better corrosion resistance.

Summary: The corrosion properties of four nickel-based cladding layers under chlorine-induced high-temperature corrosion were evaluated using the thickness loss rate. The results show that increasing the Cr content alone does not improve corrosion resistance, but instead worsens internal corrosion. The effect of Mo on enhancing corrosion resistance in laser cladding technology is closely related to its content and distribution. Transverse penetration cracks tend to occur in NiO surrounded by NiCr2O4, while the presence of short rod-like NbO2 enhances the mechanical properties of the NiO layer and eliminates such cracks.

Summary: The aim of this study is to improve the comprehensive properties of CoCrFeNiCu high entropy alloy coating (HEAc) prepared by induction cladding by means of ultrasonic impact treatment (UIT). UIT inhibited the inter-dendritic segregation of Cu atoms on the surface of HEAc, transforming the dual-phase structure to a single-phase FCC. UIT also hardened the surface of the HEAc, strengthening microhardness, elastic modulus, and wear resistance. Moreover, UIT improved the corrosion resistance of the HEAc surface by alleviating the inhomogeneity of the passivation film and promoting the growth of the film.

Summary: In this study, (TiZrNbCu)100-xNix (x = 0, 15, 25, 35 at.%) multi-principal-component alloy coatings were prepared on the surface of Ti-6Al-4V (TC4) by laser cladding to improve its wear resistance. The effect of the Ni content on the microstructure, mechanical properties, and phase composition of the coating was analyzed. The results showed that increasing the Ni content refined the grain, increased the hardness, and initially decreased and then increased the friction coefficient and wear scale. According to wear data and wear rate calculations, the Ni15 coating exhibited a wear resistance 8.2 times higher than TC4. TEM analysis revealed that the improved wear resistance was due to the changes in deformation form and strengthening phase caused by the added Ni.

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.
