Tribological Properties of Brake Shoes with Increased Phosphorus Content

The research has been conducted applying dry friction method using logs made out of brake shoes, sliding them on rotating disc out of the same material as the train wheels. Chemical composition, structure and hardness of the brake shoes and their influence on brake shoe wear were tested under simulated laboratory conditions: wheel - brake shoe. It has been found out that brake shoe wear resistance depends mainly upon phosphorus content and the structure, much more than on hardness values.
