Abstract

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. The 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 refractory 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.

With gas spraying, it is possible to apply the product to any product for any application. However, with its help, it is also possible to equip other parts of a complex form of equipment. Otherwise, spraying with gas spraying will have a lack of clarity with the base. This drawback is enhanced by the use of the base alloys, t.κ. They quickly and intensively develop the oxide film by the action of a plasma gun. Also, light alloys are critical to the high temperature of the spraying process, t.κ. The volatility of aluminum and magnesium parts can be melted, and the overheating of titanium alloys results in a decrease in their fatigue resistance.
