Studies on reduced scale tribometer to investigate the effects of metal additives on friction coefficient - Temperature sensitivity in brake materials

▶ New approach defined in this study on RSP proved to have potential to study temperature sensitivity of μ (fade and recovery behavior). ▶ This method has significant advantages such as very limited infrastructure, substantially less testing time and manpower along with extremely low cost as compared to the standard method on full scale dynamometer. ▶ Use of metallic ingredients in NAO friction composites affected all performance properties in a beneficial way. Cu was most effective in boosting TC significantly followed by brass and iron). ▶ Inclusion of metallic fillers enhanced all performance parameters related to friction and wear. Copper which is most expensive filler proved best followed by brass (moderately expensive) while iron powder (cheapest) was least effective in boosting performance of reference composite. ▶ Increased TC of the composites due to metallic fillers was the main reasons for improved friction performance.
