- Opis:
- In this study, microstructure and surface properties of low carbon steels (St52) treated by pulse plasma were investigated. The surfaces of samples were modified by pulse plasma technique. Four different plasma gun nozzle distances as 50 mm, 60 mm, 70 mm, and 80 mm and one battery capacity were chosen for surface modification. Cross-section microstructures of samples were investigated and modified layer thicknesses were measured by optical microscope. The thickness values of modified layer were obtained in a range from 10 μm to 41 μm. The samples were immersed into liquid nitrogen and then breaked in a Charpy machine. The fractured surfaces were exposed to scanning electron microscopy analyses. At the end of the study, thin grains and small tungsten grains coming from tungsten electrode were detected. After pulse plasma treatment, new structures and new phases and high hardness values were obtained.
