Description
Summary:The study of the tribological behavior of the braking system in auto vehicles reguires knowing the characteristics of the materials in contact with the friction pair, brake disc-pads, in the work process. Analysis of the materials is necessary because the wear process depends on the friction pair, and brake disk-pads, respectively on the parameters of the work process (rotational speed, pressing force, traffic conditions, etc.). The material of the brake discs is generally the same gray cast iron, but the brake pads can be semi-metallic (combination of metallic and non-metallic materials, all bonded with a special resin), organic materials (non-metallic components such as glass, rubber, and kevlar all joined with the help of a resin) and ceramic (they have only ceramic material as a composition, rarely have small copper particles). The purpose of the work is to know the crystalline structure and the mechanical properties of the brake pad materials, through specific analyses, with important implications on the friction and wear behavior.
