Unique technologies and nano-indicators

Electrochemical technologies and machines of "ET" type offered by "PЕСМ" correspond to the definition "nano" according to the following 5 categories:

Nano-metric structurization of surface

1. Formation of the surface roughness in nano-metric range (Ra=0,002. 0,01 micron, Nm =10. 100nm).
2. Formation of nano-metric geometry features on the part surface, for example:

   • At formation by copying of ophthalmologic scalpel it is possible to create (without sharpening) a cutting edge with radius of 500… 700 nanometers.

   • At copying of a regular relief, the results in a submicron range are received - the regular submicron relief with the characteristic size of (500 … 700 nanometers) is copied, that allows to create new components for human implants, medical, aviation equipment, etc. having special regular topology and geometry of micro - and nano- relief, including:

     • Creation of a special regular relief developed in depth under the set requirements (with a height and depth parity of dimples relief) on human joints implants, tooth implants, that improves biological adaptation;
     • Creation of special (with regularized microrelief) surfaces of the «sparkskin» type on blades of gas turbine engines and screw-propellers creating "Lotus-effect", increasing aero-and hydrodynamic characteristics of products.
     • Creation of special geometry of a microrelief and its orientation in various areas of contact wear surfaces for improvement of conditions of greasing keeping and decrease of friction coefficient in the direction of dominating streams.
3. Creation of nanometric (on thickness) facial layers with the changed chemical composition (as a variant, with the increased chrome content in chromiferous steels). Results of measurements show that the facial layer enriched by chrome has more smoothed microrelief and a smaller roughness. Creation of such facial layers on working surfaces of forming tools for plastic deformation, shows essential increase of their durability. Thus, in case of use of chromiferous surfaces in adjoint pairs of friction, form-building equipment (punches, matrixes), etc. the friction coefficient decreases and fatigue strength, wear resistance and corrosive resistance increase.

Processing of nanostructure metals and alloys

4. Manufacturing of precision parts from nanostructure materials of the basic groups of electrochemical machinability (steels, Ti, Al, Ni, W, Cu and their alloys, ceramic-metal nano-powdered WC-Co alloys, etc.), providing preservation of their unique nanocrystalline structures
5. Essential (in 2...10 times) increase of corrosive resistance of nanostructure materials.
