Metallic and other inorganic coatings — Automated controlled shot-peening of metallic articles prior to nickel, autocatalytic nickel or chromium plating, or as a final finish 金属和其他无机涂层——在镀镍、自动催化镀镍或镀铬之前 或作为最终饰面 对金属制品进行自动控制喷丸处理
发布日期: 1999-12-09
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 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.
