The influence of shooting conditions during shot peening of stainless steel on surface roughness

Abstract

Stainless steel AISI 316L is a suitable material used for orthopedic purposes. In order to improve the hardness of stainless steel, the heat-treatment process cannot be done, but with a shot peening process. This study aims to determine the roughness of the workpiece surface and investigate the effect of shooting conditions (i.e., angle and time) on the surface roughness during shot peening of Stainless steel AISI 316L. The shooting parameters used are 2, 4, and 6 minute for the duration, and angle of 0°, 15°, 30° and 45°. The ball material is a type of steel with 0.6mm in diameter. The experimental results presented that the increased shooting time will result in lower surface roughness, and vice versa. Therefore, it can be concluded that the use of varying shooting conditions will greatly affect the quality of the surface produced but needs to be compared with other responses, namely hardness.

Pengaruh Parameter Shot Terhadap Kekerasan dan Kekasaran Permukaan Melalui Proses Shot-Peening Stainless Steel Tipe 316

“…Hal ini menunjukkan bahwa kekasaran permukaan pada stainless steel 316 akan semakin halus jika durasi proses shot peening semakin lama. Hasil yang sama juga telah dilakukan dalam meneliti pengaruh kondisi penembakan terhadap kekasaran permukaan pada proses shot peening stainless steel [10]. Penelitian lain juga menyimpulkan bahwa terdapat penurunan parameter kekasaran permukaan Sa, Sq, S5z dan Sku pada proses shot peening 18CrNiMo7-6 steel [11].…”
