| 摘要 |
The invention relates to a composite protective multifunction coating containing light metals and alloys thereof (A, Mg, Ti, Nb, Al-Ti, Al-Be, Ti- Nb), consisting of a hard and resistant oxide ceramic layer having the form of a matrix and of a functional composition introduced into the matrix pores. T he functional compositions are selected from a group of metals (Ni, Cu, Co, Fe, Cr, Mo, Ti, Al, Sb, Ag, Zn, Cd, Pb, Sn, Bi, Zn, Ga) and/or between refractor y compositions (carbides, oxides, nitrides, borides, metal silicides of groups IV - VI of the periodic table of elements). The inventive method consists in oxidizing the base by an electrolytic plasma process, introducing the functional compositions into the pores and carrying out completion by means of mechanical treatment. The inventive coating combines the properties of strength, hardness and resistance to wear and corrosion as well as predetermined plasticity and resistance to dynamic contact loads and vibrations.
