喷丸作为一种改善金属件疲劳性能,解决应力腐蚀裂纹问题的有效工艺而被广泛采用,喷丸件还有其它方面的性能改善。尽管如此,对于喷丸参数的规定和控制并不都很了解。许多设计部门和材料部门的工程技术人员经常遇到有关丸粒尺寸、喷丸强度以及图纸规范,这些方面都关系到能否达到优质稳定的喷丸效果。本文将要解答上述这些问题,对于想制订喷丸工艺一般规范的企业来说也具有参考价值。有些公司的内订规范比较完善,但许多公司由于忽视了近年来喷丸技术领域的发展而使规范显得不够完备,如果他们想要制订规范或对原有规范进行修订,就应该向喷丸技术的权威部门咨询。对于小型公司或者不经常采用喷丸工艺的公司,可以参考一些权威性标准,美国军用标准MILS—13165—B和美国金属学会标准AMS 2430就是其中的两个。我们设想广大读者对喷丸常识及其对齿轮件的影响都有所了解,意识到喷丸是解决疲劳及应力腐蚀裂纹问题的一项有效措施,并且对整形有好处。本文只对喷丸机理作简要讨论,更详尽的资料,读者可参阅资料。
Shot peening is widely used as an effective technique to improve the fatigue properties of metal parts and solve stress corrosion cracking problems. There are other aspects of shot peening performance improvement. However, the rules and controls for shot peening parameters are not well understood. Many engineering and technical personnel in the design department and the material department often encounter the pellet size, shot peening strength and drawing specifications, all of which are related to the quality and stability of shot peening. This article will be to answer these questions, for the preparation of the general norms of shot peening process also have reference value. Some companies have a better set of internal rules, but many companies do not have a complete set of specifications due to neglect of recent advances in shot peening technology. If they want to make specifications or make revisions to their original specifications, they should give shot peening Consulting authority. For smaller companies or companies that do not often use the shot peening process, you can refer to some of the authoritative standards, the US military standards MILS-13165-B and the American Society for Metals standard AMS 2430 is one of two. We assume that most readers have an idea of the common sense of shot peening and its influence on the gear parts. We realize that shot peening is an effective measure to solve the problems of fatigue and stress corrosion cracking and is good for plastic surgery. This article only shot peening mechanism for a brief discussion, more detailed information, readers can refer to the information.
