Abstract
The brake discs of the new generation vehicles operate with very high speedand tough braking conditions. Therefore, high performance in braking isessential in terms of human and vehicle safety. In vehicles, the brakingperformance criterion is to control the speed of the vehicle safely withoutcausing a mechanical failure. During a braking process in a moving vehicle,an excessive abrasion occurs. The aim of this study was to investigate theperformance of the brake disc coated with Cr2O3-2%TiO2 (Metco106F)composite powder by using the plasma coating method to increase theabrasion resistance of automobile brake disc. The braking test wasperformed according to the SAEJ2430 braking test standard. Themicrostructure, hardness, wear and braking performance characteristics ofthe coating were investigated. Our results showed that the coated discexhibited better wear resistance than the uncoated disc under the differentwear mechanisms at high temperatures. The obtained coefficient of frictionrevealed that the coated disc showed better braking performance.
