“…Many multi-composite Ni-P coatings were prepared, including Ni-Cu-P [8], Ni-W-P [9], Ni-P-SiC [10], Ni-P-Al 2 O 3 [11], and Ni-P-B 4 C [12]. Due to the fact that copper can effectively reduce the boundary stress between matrix and surface coating, Ni-Cu-P coating shows very potential advantages in the field of anti-wear and anti-corrosion [8,[13][14][15].…”
