Abstract
The research highlights the main trends and guidance in the design of products using plastics in conditions of sustainable development of society. Plastics have an important role in the configuration of the new products still in the phase of conception. Having in view the main advantages of the utilization of plastics the expectation is to see an increase of the weighting of these ones in the products development. The present work spotlights the positive influence of the covering of the alloys with polyester. Especially it aims to increase the wearing resistance and resistance to fragility that has a direct effect on the increase of the functioning time in the total life cycle of the product. Keywords: polyester graphite, wear resistance
