对钢丸和玻璃丸的喷丸表面和表层特性进行了对比试验。采用空气喷砂机对0.45%C钢进行了喷丸强化处理。试验结果表明：钢丸的凹坑直径、表面粗糙度、硬度分布、半高宽和表面残余应力比玻璃丸高5 ~ 70%。钢丸的最大硬度和加工硬化层深度分别比玻璃丸提高4.4 ~ 8.7%和20 ~ 30%。玻璃丸处理后的表面残余应力为-260 ~-390 MPa，钢丸处理后的表面残余应力为-350 ~-420 MPa。
Several experiments were run to compare steel shot with glass shot on the characteristics of shot peened surface and surface layer. Shot peening was performed on steel (0.45%C) by an air blasting machine. The results obtained from experiments are as follows : diameter of dent, surface roughness, hardness distribution, half width and surface residual stress produced by steel shot are from 5 to 70% more than by glass shot. The maximum hardness and the depth of work hardened layer by steel shot are from 4.4 to 8.7% and from 20 to 30% more than by glass shot respectively. Surface residual stress by glass shot is from -260 to -390 MPa and by steel shot is from -350 to -420 MPa.
