The Improvement of Stainless Steel Properties after Pulse Plasma Processing

Abstract

Abstract:The results of researches of stainless steel samples surface properties after interaction by pulsed plasma streams are presented. The modification carried out on CPU-30 pulsed plasma accelerator, operated on "continuously filling" mode, by single and multiple times. The structure of material was researched by SEM and XRD methods. The evolution of the grain dimension, in depending on the basic processing parameters is investigated. The physical properties of modified material were significant chance after multiple impacts. The role of new phases and crystal size influence on process are discussed.
