The increasing interest in the emission from the disc brake system poses new challenges for the characterization approaches used to investigate the particles emitted from the wearing out of the relevant tribological systems. This interest stems from different factors. In the first place, a thorough characterization of brake wear particles is important for a complete understanding of the active tribological mechanisms, under different testing and servicing conditions. This information is an important prerequisite not only for the general improvement of brake systems, but also to guide the development of new materials for discs and brake pads, responding better to the specific requirements, including not only performance, but also the emission behavior. In this review paper, the main material characterization protocols used for the analyses of the brake wear products, with particular regard for the airborne fraction, are presented. Reliable results require investigating the fine and ultrafine particles as concerns their composition together with their structural and microstructural aspects. For this reason, in general, multi-analytical protocols are very much recommended.

碟刹材料的磨损产品的实验表征协议

盘式制动系统对排放物的兴趣日益浓厚,这对于表征方法的研究提出了新的挑战,该方法用于研究从相关摩擦学系统的磨损中排放出的颗粒。这种兴趣来自不同的因素。首先,在不同的测试和维修条件下,对制动磨损颗粒进行全面的表征对于全面了解主动摩擦机理很重要。这些信息不仅是制动系统的总体改进的重要先决条件,而且对于指导用于盘和制动衬块的新材料的开发,不仅对性能,而且对排放行为的要求也要更好地做出响应,这是一个重要的前提。在这篇评论文章中,介绍了用于分析制动磨损产物的主要材料表征方案,特别是考虑了空载部分。可靠的结果需要研究细颗粒和超细颗粒的组成,结构和微结构方面的问题。因此,通常强烈建议使用多分析方案。
