WORKPIECE STRENGTHENING METHOD

摘要

The invention relates to methods for increasing the strength of workpieces and can be used for producing different articles in aircraft, mechanical and machine tool engineering and for producing high-strength tools. The inventive method consists in applying a strengthening layer made of a material exhibiting heavy thermionic properties. Such materials are embodied in the form of a cerium a Ce and/or the heavy thermionic compositions thereof. The cerium heavy thermionic compositions have a covalence degree in the atom chemical bond ranging from 0.3 to 0.7 and the energy gap of 0
