Multicomponent coatings VPN

(monolayer, multilayer, nanostructured, gradient).

Main coatings characteristics

Microhardness 25000-45000 MPa

Thickness 1-5 mkm.

Surface rouhness not less than base.

Vivid adhesion with base.

Friction coefficient – 0,3 – 0,6.

Thermal Stability – up to 900°С.

COATING ADVANTAGES
- INCREASED TOOL LIFE
- GAINS IN PRODUCTIVITY
- IMPROVED FINISHES
- CONTROLLED TOLERANCES
- AVAILABLE ON MOST TOOLS COATED END MILLS IN STOCK

Comparative tests hard carbide cutting tools under production conditions have shown, that on identical modes of high-speed milling deterioration of mills of manufacture of firm " FRAISA ", covered nanocomposite coatings on the technologies developed by scientific and technological centre " Nanotechnology ", in 2,6-4 times it is less, than not covered.

Deposition of strengthening coatings on regrinding standard all-metal sintered-carbide cutting tool of domestic and foreign manufacturers (firm FRAISA, HANITA, PLATIT, CARLOY etc.)

Deposition of strengthening coatings of various compositions on non standart tools and furniture.

Development new and modifying of the existing coatings under concrete conditions of use of the tool and special tools and furniture.

Nanocoatings Features

Complex coating methods includingCVD, PVD, ion implantation are united in single technological cycle.

Our coatings have nanolayer structure and are composed from layers on the base of Al, Ti, Cr, Zr, Mo, and their compounds with N, C, O in different compositions. Thickness of each layer is approximately ~ 5-10 nm.

Microhardness 25000-45000 MPa (in accordance with coating composition).

Low temperature deposition processes of coatings with good adhesion to base (T≤120°С-computer controlled ).

Automated data acquisition and control system allows us to manage basic technological parameters in a very precise way.
