FIELD: electrochemical deposition. SUBSTANCE: invention refers to field of electrochemical deposition of composite coats based on chromium with microparticles of diamond which enhances hardness and prevents corrosion of cutting tools. Technical target of invention lies in creation of conditions for disaggregation of diamond particles and in achievement of synergism in rise of their sedimentation stability in chroming electrolyte. Method includes injection of aqueous suspension of cluster particles of diamond and surface active substance, its activation in disintegrator with production of dispersive mixture showing sedimentation stability in chroming electrolyte and subsequent deposition of coats on surfaces of articles. EFFECT: increased sedimentation stability of diamond particles in chroming electrolyte, increased quality of coats. 1 cl, 2 tbl
