Abstract:
Surface finish is of growing importance in shot peening operations. This paper presents data on the peening of metal surfaces of three hardnesses with different sizes of
glass beads at three specific nozzle angles. The conclusions are that when arc height peening intensity is kept constant, (1) shallower nozzle angles produce a rougher
surface texture (higher RMS value), and (2) in general, peening with smaller beads produces a smoother surface texture (lower RMS value). Also, when higher arc height
peening intensities are used, rougher surface textures are produced at all nozzle angles. Data is presented for aluminum and stainless steel surfaces with Rockwell hardness
values of 75RB, 80RB, and 89RB, showing the relationships between arc height peening intensities, surface texture and nozzle angle. Recommendations are made for proper use
of Almen arc height to control parameters of cleaning, finishing and deburring applications, as well as shot peening.
