Abstract
Recently austemopred ductile cast iron is utilized for production of gears in automotive industry in order to reduce the production costs. The problem of low hardenability of unalloyed ductile cast iron dictated the use of alloyed ductile cast iron. The present work is devoted to investigate the wear properties of austempered alloyed ductile cast iron 2% Ni, 0.5% Mo which is chosen to replace forged gears produced from carburized and hardened steel DIN 34 17220. The programme of wear tests is based on the comparison between the performance of austempered alloyed ductile cast iron and steel DIN 34 17220. Disc type wear test specimens with diameter of 40 mm and thickness 10 mm were made from alloyed ductile cast iron and from the steel. The tests were carried out at dry slidinft condition, wet sliding condition, and wet sliding plus 10% rolling. The results of wear tests showed that the wear characteristics of austempered alloyed ductile cast iron are more suitable for gear applications than the classical carburized and hardened steel DIN 34 17220.
