It is shown, that argon existing in saturated medium changes the nitriding process kinetics and the phase composition of the outer zone. Here presented investigation results on ion-plasma nitriding of instrumental steels, focused on microstructure and tool areas phase composition change, operating in most difficult conditions.

The control system of the automated laser technological complex for the technology of surfacing and hardening the cutting edge of the teeth of the mill with the positioning of the focus of laser radiation on the tooth is considered. Automating the process of laser hardening and surfacing of parts in mechanical engineering makes it possible to increase the efficiency of the technological process of tool restoration, with its specified quality indicators.

The features of laser welding technology with the help of hard-nose powders on the cutting edge of the mill with plasma cleaning of the mill surface are described here. It is shown that the quality of weld deposition technological process depends on the processing modes, the energy characteristics of the laser technological system (LTS), as well as on the purity of the router bit.

IntroductionSynthesis of uniform oxidic powder in low-temperature plasma is of special interest for the production technology of difficult oxidic chemical compounds and drew attention of many researchers because of a wide range of use in various areas of the industry. Realization of technology of synthesis of powder in plasma substantially allows increasing quality of ferritic powders. This approach allows to solve many production problems. This decrease in multistaging of technological process, its duration, increases of indicators of quality, etc. [1].The conducted researches in this direction are caused by [2] relevance of synthesis of oxidic powder in nonequilibrium low-temperature plasma with the set quality indicators. The presented results allow to judge the correct approach in the solution of an objective. This way based on application of a plasmatron with the nonequilibrium gas category with liquid electrodes was investigated by a number of authors [1,3], however in their results properties of the received oxidic powders aren't presented. Therefore the purpose of researches is synthesis of oxidic powder in nonequilibrium low-temperature plasma with the increased quality.
