| Abstract Scope |
The level of gray cast iron and steel parts performance characteristics subjected to diffusion metallization is determined by the set of the saturated layer parameters: depth, phase composition and distribution, porosity, structure of the sublayer and layer. Based on the mathematical models obtained the "diffusion property – mixture composition" diagram are constructed, which allow to determine the optimal composition of the saturating mixture.
It is established that during diffusion titanium plating the optimal amount of cadmium chlo-ride in the saturating mixture is 6…10%. It is established that the diffusion titanium saturating mix-ture, containing 8…10% aluminium, provides the high-quality surface coating having a continuous carbide layer.
In diffusion chromium plating the presence of ferromanganese in the saturating mixture in-creases the diffusion layer relative wear resistance coefficient for steel by 10…15 times, for cast iron by 20…25 times relative to the diffusion layer obtained in the mixture that does not contain ferromanganese. |
