标准摘要
[中文适用范围]： 本国际标准描述了在电解或自催化沉积镍或铬之前，或作为最终表面处理，使用铸钢丸、经过调节的切割钢丝、陶瓷丸或玻璃珠对金属制品进行自动、受控喷丸的要求。 该过程适用于那些测试工作表明其在给定强度范围内有益的材料。 它通常不适用于脆性材料。 手动喷丸和旋转翻板喷丸被明确排除。 喷丸在金属制品的表面和近表面层中产生残余压应力，并改变表面微观结构（包括相变），从而控制或限制制品镀镍或镀铬导致的疲劳性能下降，或提高未电镀制品的疲劳性能。 [外文原描述]： This International Standard describes the requirements for automated, controlled shot-peening of metallic articles prior to electrolytic or autocatalytic deposition of nickel or chromium, or as a final finish, using shot made of cast steel, conditioned cut wire, ceramic shot or glass beads. The process is applicable to those materials on which test work has shown it to be beneficial within given intensity ranges. It is usually not suitable for brittle materials. Handpeening and rotary flap-peening are specifically excluded. Shot-peening induces residual compressive stresses in the surface and near surface layers of metallic articles, and changes the surface microstructure (including phase transformation), thereby controlling or limiting the reduction in fatigue properties that occurs from nickel or chromium plating of the article, or increasing the fatigue properties of unplated articles.
