Abstract:
In view of the current situation in the mining sector, with high added value of iron ore, it is necessary to increase productivity, avoid waste and create mechanisms that obtain the maximum potential of assets without defining them at risk, maintaining socio-environmental responsibility. Through this vision, after studying the biggest expenses with replacing the friction elements of the brake system of the equipment for the road, this work began in which it was determined which materials are the most cost effective for our operation. Thus, four different types of friction sets used in truck brake systems for the road, from different manufacturers, were tested for wear resistance in order to estimate which of the sets have greater durability in the field. For this, the materials were tested in a tribometer in the pin-to-disc configuration, where the pin is the steel plate and as a disc, or friction disc. Track wear was measured after the test using confocal microscopy. Finally, the wear results and the friction coefficient of the materials were extracted and compared to determine the most cost-effective material for an operation.
