标准范围

本国际标准描述了金属制品自动控制喷丸的要求在电解或自动催化沉积镍或铬之前，或作为最终饰面，使用铸件制成的喷丸钢、经过处理的切割线、陶瓷丸或玻璃珠。本工艺适用于需要进行试验的材料研究表明，在给定的强度范围内，它是有益的。它通常不适用于脆性材料。手工喷丸特别排除旋转皮瓣喷丸。喷丸处理会在金属制品的表面和近表面层产生残余压应力，以及改变表面微观结构（包括相变），从而控制或限制工件镀镍或镀铬产生的疲劳性能，或增加工件的疲劳性能未发布的文章。

This International Standard describes the requirements for automated, controlled shot-peening of metallic articlesprior to electrolytic or autocatalytic deposition of nickel or chromium, or as a final finish, using shot made of caststeel, conditioned cut wire, ceramic shot or glass beads. The process is applicable to those materials on which testwork has shown it to be beneficial within given intensity ranges. It is usually not suitable for brittle materials. Handpeeningand rotary flap-peening are specifically excluded.Shot-peening induces residual compressive stresses in the surface and near surface layers of metallic articles, andchanges the surface microstructure (including phase transformation), thereby controlling or limiting the reduction infatigue properties that occurs from nickel or chromium plating of the article, or increasing the fatigue properties ofunplated articles.
