CHANGE THE SIZE AND SURFACE ROUGHNESS SAMPLES OF STEEL St3 IN DIFFUSION SATURATION OF BORON, CHROMIUM AND TITANIUM Guriev A.M., D.Sc.

Polzunov Altai State Technical University, 46 Lenina avenue, Barnaul, Altai region, 656038, Russian Federation 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. Keywords boron, chromium, titanium, boriding, steel, coating, diffusion
