Advanced Technologies

(a) The technologies for special coatings when the electrochemical technological processes are not applicable due to the necessity to use dry deposition methods including vacuum sputtering:

• Deposition of heat resisting protective coatings from alloys containing Cr, Ni, Co, Y, Al, Rare metals onto the parts of internal-combustion and turbo-jet engines; the thickness of coatings = 3-50 microns; method of deposition: magnetron sputtering + ionic implantation + impulse treatment by electronic beams.

• Deposition of special composite coatings from Me-C, Me-S, Me-Si, Me-B, etc onto the parts and tools exploited in the extreme conditions of wear, friction, erosion, etc; the coatings are of high hardness up to Hv= 5000 êg/mm², low coefficient of friction = 0,15-0,01, low oxidizability in the current of pure oxygen at the temperature up to 1000 ^îÑ; method of deposition: magnetron sputtering of mosaic targets + impulse treatment by plasma beams.

(b) The alternative pollution free technologies to replace widely used environment contaminating technologies:

• Replacement of electrochemical deposition of Cr, Ni, Co, Cu, brass, Sn, Zn, etc by vacuum sputtering of these metals + other materials which cannot be galvanized, such as: austenitic 18-10 steels, high-alloyed austenitic steels, Ni-based alloys, Cr-Ni alloys, Cr-Al alloys, Cr-Ti alloys, austenitic steel + Cr + Al, Cr-Al-Y alloys, Ni-Ti alloys. The parts coated are made of ordinary steels, low-alloyed steels, Ti- and Al- alloys, plastics. The coatings are corrosion resistant and possess high micro hardness Hv up to 1400 êg/mm²; nano-crystalline structure; higher wear- and acid-resistance, resistance to the melts of Na, Pb, Bi. The methods of deposition: magnetron sputtering of mosaic targets + treatment of surface by impulse electron or plasma beams.

• Replacement of electrochemical anodizing and oxidizing by the vacuum deposition technology combined with the supply of reactive gases: oxygen and nitrogen to get the oxides, oxide-carbides, nitrides coatings of the given thickness and color due to the sputtering of Ti, Zr, Al, Cr, Al-Ti, Ai-Zr and other complex alloys containing: Ni, Y, Cr, Co, Hf, V, Si, Fe onto the parts made of Ti, Al and other materials;  the coating thickness: 0.01-10 microns and more. The methods of deposition: vacuum-arc and impulse magnetron sputtering + treatment of surface by impulse electron beams.
