The process of modeling the production of alitized, titanium, siliconized, nickeled coatings is an effective method to increase the reliability and durability of machine parts, tools, and tooling due to the creation of protective layers on the surface of the machined parts that have a unique set of physicochemical properties.

One of the most efficient methods of the development covering, possessing high mechanical, physic and chemical characteristics is surface metal diffusion saturation using a composite powder materials.

The alloys based on copper served the source data for study. The diffusion method of the surface saturation from hard phase in active gas ambience on the basis of analysis of the requirements, presented to copper covering and the way of the metal saturation for defensive covering obtaining has been chosen. This method provides for high surface quality and it is the simplest and most suitable one in laboratory practice being well reproduced in production condition and it does not demand for special complex equipment whileь it’s realizing.
