T. IIZUKA and K. IKEDA Tochigi Works Hitachi, Ltd. Shimotsuga-gun, Tochigi-ken, Japan, 329-44 Since applications of rotary compressors driven by inverter motors have become more widespread, l~bricating problems with the sliding parts have been appearing. The sliding parts require sufficient antiseizure and wear-resistant properties under the boundary lubricating conditions. The authors have dev...

Molecular dynamics simulations are used to explore the atomic-scale chemistry and associated wear that occurs when diamond surfaces are placed in sliding contact. The simulations predict complex radical chemistry initiated by the shearing of hydrogen atoms from chemisorbed molecules. Observed chemical mechanisms include hydrogen abstraction from the surfaces, radical recombination, transient su...

Wear of elements subjected to friction and sliding is among the main causes of low tribological performance and short lifetime of strategic materials such as titanium alloys. These types of alloys are widely used in different areas such as aerospace and the biomechanics industry. In this sense, surface modification treatments allow for the overcoming of limitations and improvement of features a...

Influence of formation of surface nano/ultrafine structure using deep rolling on plasma nitriding and tribological properties of the AISI 316L stainless steel was investigated. Initially, the deep rolling process was carried out on the bar-shaped specimens at 15 cycles with 0.2 mm/s longitudinal rate and 22.4 rpm bar rotation. Then, plasma nitriding treatment was applied on the as-received...
