For the increase of capacity of instrument presently the basic method of consolidating is by volume heat treatment. However practically always heat treatment results in the sharp decline of viscidity and трещиностойкости and, in this connection, to premature death instrument by reason of fragile destructions. The increase of operating properties of instrumental materials is possible also at the use of methods of the superficial consolidating - induction tempering, Chemicaly - thermal treatment, causing of coverages. Advantage of these methods by comparison to by volume consolidating is achievement of the required high values of wearproofness only in relatively thin superficial layer, while the core of instrument can remain in the soft and plastic state. High-quality the new level of operating properties of instrumental materials is arrived at attreatment of heating (HCS) high concentrated sources - by laser and electronic rays, plasma stream. Due to local and сверхскоростному thermal influence possibilities of receipt of more high values of hardness, durability, viscidity by comparison to by volume treatment or traditional methods of the superficial consolidating are created. It is conditioned foremost education in the superficial layer of high dispersion mehtastable structure with far more high closeness of distributions. From the methods of consolidating of HCS more economical, productive and accessible there is the plasma consolidating. Hardness carbon and низколегированных instrumental сталей after the plasma consolidating exceeds on 100...200 HV hardness after by volume tempering.
