Technological Ion-Plasma Devices and Vapor Deposition Technique for Hard-to-Reach Surfaces

Description

Technological ion-plasma devices for vapor deposition technique for hard-to-reach surfaces of tubular items are developed. With this “dry” technology use it is possible to deposit wide range of coatings, and the technology is ecologically appropriate. Developed ion-plasma devises allow ion beam matching of the surface and deposition of internal hard-to-reach surfaces with 25 mm diameter. There are no limits for the treated item length. Causing by multilayer nano-composite and superlattice type coverages from any metals, alloys and chemical compounds is also possible. The thickness of one-layer deposition is up to 0.1 mm. Coating condensation temperature is 250-400°С. Surface roughness corresponds to the padding roughness. Specific deposition rate is about 1 mcg/J.





Innovative Aspect and Main Advantages

The technology is ecologically appropriate and is alternative to chemical galvanic and thermal overcoating technologies, it possesses universal possibilities of causing by different composition and usage functional coverage to the internal and external surfaces of axisymmetrical details. It gives the advantageous distinction from other electrophysics ways of surface modification and also from mechanical technologies of surface plastic deformation type.

Areas of Application

Friction elements working in the responsible devise units in increased corrosion and mechani-cal wear conditions. The technology can be used by enterprises of aviation, transport, mining machine building.


Stage of Development

Samples of the plasma technological devices and a prototype of the industrial plant are made for the treatment of working surfaces of friction pairs like “cylinder – piston” from high strength titanium alloy. There is a patent of Ukraine for the useful model. Chromic coating has been inflicted to the internal surface of titanic hydro cylinder of AN 148 aircraft hydrosystem with 32 mm diameter, 250 mm length, 30 mcm covering thickness and 0.2 mcm roughness. The coated detail successfully passed stand tests during 75 400 model flights that exceeds aircraft life period.
