请教一下，shot blast和shot peening有什么区别？

 “Shot Blasting”与“ shot peening”之间“定义”“介质使用”和“

应用”都不相同。简单总结如下：

Shot Peening is a metal finishing process similar to Shot Blasting, but it differs slightly in process and the by-products created. The main difference between blasting and peening is that blasting relies on an abrasive process which chips pieces of the product away, whereas peening relies on the plasticity of the process. Plasticity is the ability of the product to be bent or to be pounded into a different shape. Since it is not abrasive, peening will remove less material from the product and produce less dust.

大意：shot peening是一种金属精加工过程类似于Shot Blasting，但在过程和副生产品上会稍有不同。两者间主要区别是，blasting 依靠磨料过程将产品屑片移除，而 peening是针对产品可塑性的过程。这里所说的可塑性是指产品折弯或捣碎成不同形状的能力。可见 peening 不是磨料过程，它从产品中去除材料较少并产生粉尘较少。

如果需要二者“定义”“介质使用”和“应用”的详细比较，请见下表：
