Summary: In this study, Ni-based alloy/nickel-coated graphite composite coatings with the addition of titanium were successfully claded on 300M ultra-high strength steels by laser to improve their wear and corrosion resistance. The titanium-containing coatings exhibited higher and more homogeneous microhardness, as well as better wear and corrosion resistance compared to the titanium-free composite coatings.

Summary: Ni60-5%Ti3SiC2, -10%Ti3SiC2 and -15%Ti3SiC2 coatings were prepared on S355 steel by laser cladding. The microstructure, phases, and hardness of the coatings were analyzed. The Ni60-5%Ti3SiC2 coating showed the best tribological performance with increased friction stability and reduced COF and wear rate compared to the substrate. The wear mechanisms of the coatings were identified as abrasive wear, adhesive wear, and abrasive wear for Ni60-5%Ti3SiC2, Ni60-10%Ti3SiC2, and -15%Ti3SiC2 coatings, respectively.

Summary: In this study, the influence of laser-ablated cracks in microdimples on the corrosion properties of Ni60/WC coating is investigated. It is found that when the apparent microcrack does not extend to the substrate, the nanosecond laser ablation of microdimples does not change the coating corrosion properties. Moreover, the corrosion properties of the coating are improved by laser ablation recrystallization.

Summary: In this study, the microstructure and properties of WC/Ni60 composite coatings by laser cladding were improved through multiple laser shock peening treatments, which effectively enhanced the wear resistance and corrosion resistance of the coatings. After three times of laser shock peening, the average grain size of the coating was reduced by 12.9%, all residual tensile stresses were transformed into residual compressive stresses, the wear rate was reduced by 27.5%, and the self-corrosion current density was reduced by 77.1%.

Summary: The study investigated the cracking susceptibility, microstructures, and wear resistance of coatings with different dilution rates by altering the processing parameters. It was found that the dilution effect of the eutectoid steel substrate increased with the increase of laser beam power, leading to composition deviation of coatings. Microhardness of the coatings increased with the dilution rate but excessive dilution resulted in severe cracking defects. The optimized cladding coating with a dilution rate of about 48% exhibited improved microhardness and wear performance due to increased carbon content.

Summary: In this study, laser surface alloying of commercially pure copper (cp Cu) with Cr/Ti and Cr/Ti/CNT was conducted, and the effects on hardness, wear resistance, and corrosion resistance were investigated. The results showed that the laser-alloyed specimens had higher hardness and improved wear resistance compared to pure copper. The corrosion resistance of the laser-alloyed specimens was also better due to the presence of passive Cr and Ti.

Summary: The study investigates the properties of Ni-B-GO composite coatings on low carbon steel using pulse electrodeposition, with graphene oxide (GO) as reinforcement. Results show that increasing GO content decreases both the friction coefficient and indentation depth of the coatings, with GO acting as a lubricant during friction and wear tests. The wear mechanism is identified as adhesive wear, and the corrosion potential of the composite coating decreases with higher GO content.

Summary: In this study, Ni-modified graphene powders were synthesized by electroless plating method and used to prepare Ni60-Ni@Gr composite coatings, enhancing the application of graphene in laser cladded coatings. The modification improved the wettability between the metal matrix and graphene, leading to better dispersion of graphene nanosheets. The Ni60-Ni@Gr coatings exhibited higher micro-hardness, improved wear resistance, and enhanced corrosion resistance compared to Ni60-Gr coatings and Ni60 coatings, attributing to the excellent barrier property of uniformly dispersed Ni@Gr powders in the coatings.

Summary: Ni60-4%Ti3AlC2, -8%Ti3AlC2, and -12%Ti3AlC2 composite coatings were prepared on S355 steel by laser cladding, and their corrosion behavior and electrochemical performance were analyzed. The Ni60-Ti3AlC2 composite coatings are composed of various phases, and the grain size becomes finer with increasing Ti3AlC2 mass fraction. The Ni60-12%Ti3AlC2 composite coating has the best salt spray corrosion resistance due to the formation of α-Al2O3 and TiO2 oxide films.
