The paper presents the results of investigation of surface changes taking place after the process of gouging with air plasma. The investigation included the assessment of the plasma current influence on the structure and hardness of metal sheets with the thickness of 6, 12 and 16 mm. It has been found that, in the process of gouging, both the value of the plasma stream intensity and the thickness of the material significantly influence the properties of the top layer and the size of the formed grooves. The existence of two surface zones has been proved: the zone of melted metal and the heat affected zone. It has been determined that increase of the plasma stream intensity, with constant sheet thickness, results in an increase of the gouging depth. . It has been proven that the increase the sheet thickness for constant plasma currents influence for decrease in the depth of the gouging grooves. |
