“…Aluminum and its alloy are attractive for many applications in chemical, automobile and aerospace industries, owing to their high strength-to-weight ratio, high electrical and thermal conductivities, and excellent corrosive resistance in some severe environment [1]. However, the lower hardness and the worse wear resistance greatly limited their application.…”

“…[14][15][16][17][18][19] It is noticed that substrate materials include steel, Al-Mg alloy, Mg alloy, etc., whereas reinforcements are mainly ceramic particles, such as Al 2 O 3 , TiC, and TiO 2 , etc. However, the application of powder metallurgy materials as substrates, in particular, the use of nanomaterials or nanoparticles as reinforcements of laser cladding layer, has never been reported in the literature.…”

Surface laser cladding using CO 2 laser beam irradiation was used to develop iron-based powder coatings containing nano-Al 2 O 3 particles. The microstructural and mechanical, in particular, tribological, behaviors of the developed materials were investigated by means of scanning electron microscopy (SEM), energy-dispersive spectroscopy, and X-ray diffraction as well as Vickers microhardness and friction and wear testers. It was demonstrated that mechanical properties, especially, the wear resistance of the material, can be significantly improved with the addition of the nano-Al 2 O 3 particles due to the refined grains on surfaces and the dispersion strengthening and hardening of nano-Al 2 O 3 particles. The detailed mechanism responsible for such unique wear performance was further discussed. The current study provides a potential simple and practical technique for the development of stable nanomaterials.

“…Compound powder has many kinds, and the composite ceramic powder has the advantages of high strength, wear resistance, low coefficient of expansion, and so on. It has been widely studied and applied [3]. R. Anand Kumar et al [4] mixed Al-12% (mass fraction, the same below) Si alloy powder and TiC powder, and then clad them on the surface of Al-7% Si casting alloy by Nd:YAG laser with continuous wave; the microstructure of the cladding layer was observed and analyzed, and the sliding friction and wear test were carried out in the coating with less than 5% void and no other defects.…”

In this paper, Al/Ni/TiC powders were mixed on the surface of A380 aluminum alloy, by selecting appropriate laser parameters; the cladding layer with good adhesion to the substrate was obtained. The microstructure and properties of the cladding layer under different laser parameters were analyzed. The results show that: the phase composition of the cladding layer is mainly composed of TiC, Al, Ni, C and Ti phases. The hardness of the cladding region is up to 173.3 HV, which is about 2.9 times the matrix (−59.1 HV). The corrosion voltage (−1.8 V) of the cladding layer shifted significantly from the corrosion potential (−1.18 V), the corrosion current density increased, the resistance value decreased and the diameter of the capacitor arc decreased; all these phenomena indicate that the corrosion resistance of the cladding layer is decreased.
