Evaluation of the Effectiveness of the Shot Peening Process for Thin-Walled Parts Based on the Diameter of Impressions Produced by the Impact of Shot Media

Abstract

The paper presents the results of studies on the effectiveness of the shot peening process for thin-walled parts based on the diameter of impressions produced by the impact of shot media. It is also described the current applications of this treatment for the thin-walled parts. The authors described an innovative measuring device which was used in the research. The material used in the studies was non-alloy steel C45. The relationships between beads diameter and thickness of workpieces on diameter of impression were presented.

Optimasi Parameter Gravitasi Shot Peening Terhadap Kekasaran, Kekerasan dan Struktur Mikro ST 45 dengan Metode Taguchi

“…Berdasarkan penggunaan faktor yang optimal pada penelitian sebelumnya maka untuk optimai proses shot peening yang diteliti menggunakan variasi jarak 50, 100, dan 150 mm, variasi waktu 5, 10, 20 menit, variasi tekanan udara 5, 7, 9 kg/cm² dan menggunakan bola baja 0,8 mm dengan pengujian terhadap sifat kekerasan, kekasaran, keausan, dan struktur mikro pada material ST 45. Proses shot peening dapat dilakukan dengan beberapa parameter yang berpengaruh seperti variasi ukuran bola baja, tekanan penembakan, jarak antara nozzel dengan benda uji, waktu shot peening dan beberapa parameter yang lain, [6].…”

The Properties of Regenerative Polymer Mass

“…surface roughness. This is done by mechanical processes such as abrasive blasting or grinding using different tools and methods [18,19,21,25,29].…”

The effect of vibratory and rotational shot peening and wear on fatigue life of steel

“…The findings of tests conducted by the positron annihilation method demonstrate that the distribution of residual stresses is connected with evolution of crystalline structure defects concentration [20]. As in the case of static burnishing, the effect of shot peening greatly depends on the properties of material subjected to shot peening, workpiece shape, geometrical structure of the surface prior to shot peening, tool design and technological parameters [5,9,18].…”
