Abstract
The evolution of the studied sample sizes and masses of steel St3 depending on deposition
process parameters of multicomponent of diffusion coatings based on boron, chromium and
titanium. Growth steel specimen dimensions substantially independent of the composition of the
saturating medium and the method saturation. The size increase an average of 0.12 mm for every
100 microns thickness of the diffusion layer. The surface roughness of the samples of steel St3
depends on the composition of saturating medium and the saturation method.
