“…They lack crystal defects such as vacancies, dislocations, and stacking faults and therefore possess advantages such as high hardness, wear resistance, and corrosion resistance. The fast cooling rate of laser cladding makes it possible to apply amorphous materials to laser cladding [82][83][84][85][86].…”

As one of the lightest structural metals, the application breadth of aluminum alloys is, to some extent, constrained by their relatively low wear resistance and hardness. However, laser cladding technology, with its low dilution rate, compact structure, excellent coating-to-substrate bonding, and environmental advantages, can significantly enhance the surface hardness and wear resistance of aluminum alloys, thus proving to be an effective surface modification strategy. This review focuses on the topic of surface laser cladding materials for aluminum alloys, detailing the application background, process, microstructure, hardness, wear resistance, and corrosion resistance of six types of coatings, namely Al-based, Ni-based, Fe-based, ceramic-based, amorphous glass, and high-entropy alloys. Each coating type’s characteristics are summarized, providing theoretical references for designing and selecting laser cladding coatings for aluminum alloy surfaces. Furthermore, a prediction and outlook for the future development of laser cladding on the surface of aluminum alloys is also presented.

“…The material of the hardness is over HRC 70. [1] WC has been widely used in manufacturing for various applications, including molds and dyes, cutting tools, wear-resistant components, and coatings. WC often faces problems with the grinding wheel's wear and brittleness and the roughness of the surface of the workpiece during the grinding process because of its material behavior.…”

Tungsten carbide (WC) has been widely utilized in recent years in the hardware, mechanical, and chemical industries and in national defense because of its high hardness, anti-wear, low temperature, and anti-corrosion properties. However, using it for grinding is also challenging because the WC material has high hardness and brittle characteristics. The typical hub of a diamond wheel is made of steel. In high-speed grinding, the steel hub of the diamond wheel is subjected to gravity and centrifugal forces, which cause grinding wheel vibration, poor workpiece processing quality, and a short machine life. Therefore, this study used a carbon-fiber-reinforced thermoplastic (CFRP) hub to replace the steel hub when grinding the WC workpiece. It aimed to investigate methods to reduce oscillation, improve chip efficiency, and increase accuracy in the WC workpiece. The research results demonstrated that using a CFRP hub in the grinding wheel can reduce the oscillation when the peripheral speed of the grinding wheel is at 20–100 m/s. Additionally, the surface roughness average (Ra) of the workpiece can be reduced to 3.2–25.4% and the ten-point height of irregularities (Rz) can be reduced to 18.9–44% compared to using a steel hub in the grinding wheel.

“…Fe-based alloy cladding materials, within the self-melting alloy system, have found extensive use in surface modification of low and medium-carbon steel owing to their close composition with the carbon steel matrix, significant co-grid effect, strong interfacial bonding, and cost-effectiveness [9]. However, their current limitations lie in poor self-melting and oxidation resistance, leading to cracks and porosity in the fused cladding layer, ultimately compromising its performance.…”

In this study, a WC-Fe-based coating was prepared on 45 steel substrate utilizing laser clad-ding technology. To optimize the composition of the Fe-based alloy powder, a thorough anal-ysis of the cracks observed during the formation of the cladding layer was conducted. Ele-mental control of the WC-Fe-based alloy powder was employed to mitigate issues such as porosity and slagging, consequently reducing susceptibility to cracking. The optimized WC-Fe-based alloy coating exhibited enhanced wear and abrasion resistance when compared to the widely used Ni45 coating. Microstructural investigations revealed that both coatings fea-tured dendrites, cellular crystals, and equiaxial crystals. However, the WC-Fe coating dis-played a finer and denser microstructure, highlighting its superior characteristics. The hard-ness and abrasion resistance tests demonstrated exceptional performance of the WC-Fe-based coatings, boasting approximately three times the substrate's hardness and a wear rate approx-imately seven times lower than that of the substrate. The coefficient of friction for WC-Fe-based coatings remained consistently stable at approximately 0.4, indicative of remarkable friction reduction and abrasion resistance.
