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.

Specific features of the formation of welded metals under the pulsed action of laser radiation are described. It is shown that the quality of the technological process of welding depends on the energy characteristics of the laser technological complex, the temperature of the surface layer. The results of experimental studies on the effect of pulsed laser radiation on steel 08YU with the possibility of obtaining a welded seam with the required quality indices are presented.
