Technology of surface strengthening of machine parts

Description

The technology of surface mechano-pulse treatment of machine parts, using the energy of high-speed friction has been developed at Karpenko Physico-Mechanical Institute NASU. It forms in the near-surface layers of machine parts the nanocrystal structures of high hardness and wear-resistance with low friction coefficient. This treatment can be used for strengthening of cylindrical and flat-face surfaces of steel and cast-iron parts. We can manufacture parts with application of this technology and implement it at the client’s site. At a number of plants this technology has been used for strengthening of unloading lops and discs, bushes, seats and discs of drilling pumps, conveyor and elevator pins , hydrocylinder rods and other.

Innovative Aspect and Main Advantages

  • strengthening of cylindrical and flat-face surfaces of steel, and cast-iron parts;
  • improvement of service life of machine parts;
  • preservation of high surface quality (used as a finishing technological operation);
  • hardness and wear-resistance of elements increases etc.
  • simple realization and no large capital investment is necessary.

Areas of Application

  • Machine building;
  • Oil and gas, extracting industries;
  • Metallurgy;
  • Communal services;
  • Investigations etc.
