Abstract
The surface of AISI 316L was treated by shot peening at different shot durations. Shot peening variables in this work are shot durations for 0, 4, 10 and 20 minutes, with compressor pressure at 8 kgf/mm(2), steel balls with a diameter of 0,6 mn and shot gun nozzle diameter of 5 mm. The purpose of this research is to investigate the shot peening effect duration on surface roughness, hardness, and fatigue-corrosion characteristic of AISI 316L in 0 9 To NaCl solution The results show that the duration of shot peening can affect the improvement on surface roughness, hardness: wettability and fatigue-corrosion life of AlS1316L.
