Surface cleaning

   The surface of a material is continually exposed to its environment and is, therefore, saturated with the elements present in it, which is yet another source of inhomogeneity of its chemical composition. For instance, a surface exposed to the atmosphere has a higher content of carbon and oxygen. The presence of the latter is known to decrease the electrical and chemical resistance of materials. An electron-beam treatment by intense pulsed electron beam generated on the RITM machine essential decreases the concentration of these elements in the near-surface layers.
