The parameters of electrolytic synthesis of Ni-P coatings on steel surface from sulfate-chloride electrolyte have been determinated. The Ni-P alloys consist of separate phases of Ni and Ni3P and solid solution of implementation on the basis of the FCC Ni lattice, when it was deposited from the electrolyte at current density to be more than 7 A/dm2. The coating was formed with continuous globular surface at current density of 5 A/dm2. The globular formations are the Ni3P phase. The obtained at current density of 9 A/dm2 coatings have maximum value of micro¬hardness 430 HV
