Abstract
The purpose of this work is to experimentally prove the possibility of modifying the surface of a material by exposure to a long-lived plasma formation (DPO). Under this action, the surface of the material experiences heat shock, since the contact time is about 100 ms. The paper deals with the usage of autonomous long-lasting plasm formations (DPO). The tasks of thermal processing, coating, thermal shock tests metallic and non-metallic materials are introduced in the given paper. Large stored energy (till 10 kJ) and high brightness temperature (4 500 K) at sufficient time of influence can determine the range of technological problems, where long-lasting plasma formations have advantages in comparison with plasmatrons. This paper presents the results of the tests of the thermal shock by the concentrated flow of electromagnetic energy, saved by long-lasting plasm formation.
