Friction and wear of several kinds of cast irons under severe sliding conditions

Investigation of Tribological Behavior of Stainless Steel 304 and Grey Cast Iron Rotating Against EN32 Steel Using Pin on Disc Apparatus

“…They also pointed out that the excellent wear resistance of grey cast iron during dry sliding under low loading conditions was attributed to graphite flakes and formation of a graphite film. Hirasata and Hayashi [6] studied friction and wear of several kinds of cast irons under severe sliding conditions and found that the wear rates were strongly dependent on hardness variation. No tribooxides were noted to exist, only a plastically deformed layer.…”

Characteristic Evaluation of Brake Block Material

“…The sliding contact between the specimen pin and disc also generated heat that increased the temperature on the specimen pin. The hardness of the cast iron pin decreased with an increase in temperature, such that this condition reduced the shear strength and enhanced the wear rate of the specimen [19]. The big arrow in Fig.…”

“…The results revealed that the coefficient of friction of C-MBB decreased with an increase in the contact pressure and sliding speed. The decrease in the coefficient of friction with an increase in the sliding speed was attributed to the fact that the hardness of the cast iron at the contact surface decreased with an increase in the sliding speed [19].…”

Anti-wear properties on 20CrMnTi steel surfaces with biomimetic non-smooth units

“…The heat treatment process is controled severely to avoid the micro-cracks and hardness scarcity resulting in failure of the gear. The friction and wear are unavoidable for mechanical components during the operations [5][6][7]. Inspired by the cuticles of soil animals (such as dung beetles, black ants and pangolins), a bionic method was studied recently to improve the anti-wear property of mechanical part surfaces because the cuticles of soil animals can provide excellent anti-wear properties against soil [8,9].…”
