Application of new technologies to improve the exploitation properties of combustion engine pistons of aluminum alloys

This paper presents the application of new technologies in order to improve the exploitation properties of pistons for combustion engines made of aluminum alloy. Modern development of internal combustion engines, especially in the case of sports cars, imposed by the need to achieve maximum power, which in turn extremely increases the load on the individual parts of the piston. It has been shown that the hardness and wear resistance, otherwise inherent in aluminum alloys, for such high temperatures and extreme service conditions are not satisfactory. The idea is to protect the most burdened parts piston with aluminum matrix composites, which would be a solution to this problem. The aim of this paper is to review the research results achieved in this area.
