Abstract:
      To investigate the changes in the microstructure and properties of Ni-SiC composite coatings when SiC particles gradually transition from the micrometer scale to the nanometer scale, and to analyze the influence mechanism of SiC particles at different scales on Ni-SiC composite coatings. This article uses direct current electroplating to prepare various Ni-SiC composite coatings containing SiC particles of different scales on pure Al discs with a diameter of 20 mm and a thickness of 2 mm, with SiC particles of 3 different sizes (2 μm, 500 nm, and 40 nm) as raw materials, through single addition and combination addition methods.
