• Electrochemical corrosion (chemical instability)

  Steels and cast irons can be called solid solutions of chemically instable elements. The electrochemical corrosion is the most destructive factor for friction and contact surfaces. In all mechanisms all parts are made of materials, including metals, with different chemical composition. In service the parts are rubbing with different relative dicplacements. As a result, in friction and contact zones due to inhomogeneity of the metal structure in the presence of an excellent electrolyte (oil) there emerge electromagnetic fields in microvolumes, which create perfect conditions for electrochemical corrosion procedure.

• Hydrogen embrittlement (cracking)

  This factor is intrinsic to the nature of metals and methods of production thereof. The existing remedies are highly expensive.

• Inability to "dry" friction

  Practically all existing today constructions are provided with lubrication systems and sealing arrangements. Eventually not a single sealing design proves capable of containing lubrication within crankcases at "gland-shaft" contact due to electrochemical corrosion. All this leads to low wear resistance and inability of the existing to date constructions to "dry" friction (friction without oil), which makes steels and cast irons readily fuse over the surface due to microwelding between the microrelief projections.

• Loss of structural strength and surface annealing with relatively low heating
• Great weigth of parts, articles

The XADO-technology treatment includes a number of process operations, targeted at attainment on friction and contact surfaces of machine parts of a cermet protective coating of a thickness sufficient to compensate the wear by utilization of XADO reconditioning compound.

The positive results of such treatment are obtained, if on the rubbing surfaces of any mechanism there will be delivered and worked on a required quantity of said reconditioning compound over the required time.
