In the work it is shown that the design of combined technological processes ensuring the maximum possible operating characteristics of products assessed in a criterion way is possible. The science-based methods of choice and use of technologies created earlier, methods for the development of promising coating types, means for the modification of a surface layer and thickness changes of coatings with operating characteristics required are shown. The possibilities are considered for the creation of new methods realizing operating indices the fulfillment of which is impossible at common technologies. The well-known researches have shown that at the operation of science intensive products the mechanical characteristics including fatigue material resistance depend to a great extent upon a state and properties of a surface layer that is why there is offered a substantiated choice and design of technological processes for manufacturing products with properties corresponding most completely to operation conditions.
