The effect of SiC dispersed silicon carbides SiC additive (1.0 g/l) on formation of high (more than 1000HV) microhardness and defectiveness of the nickel-phosphorus coating of the steel parts used in critical assemblies and mechanisms at transportation of oil and mineral oil was evaluated. It is established, that regardless of SiC presence in the structure, the coating crystallizes with formation of identical microhardness level. However, the addition of SiC can drastically reduce the heat treat
