Abstract
Abstract. Due to the high performance, lightweight, competitiveness and net shape of the parts produced using sintered Powder Metallurgy (PM), PM-based products are used in different industrial applications. PM method offers high precision and repeatability, maximum material utilization, tailored shape properties, freedom of design, cost efficiency, and sustainability. These advantages are driving the ongoing demand for PM products and for the PM method as a good alternative to the conventional gear production methods. The use of PM is confirmed as an applicable technology for gear production. However, the strength and NVH characteristics of PM-products still require more investigation. In the current paper, the mechanical properties, strength and NVH characteristics are presented and discussed. The paper concludes based on the presented overview of the applicability of PM gears in the industry, further research investigation is needed on both the system and component levels to improve the durability and NVH behavior which are important for extending the PM parts’ application. Moreover, the sustainability aspects of powder metallurgy technology should be emphasized.
