...X. Fan; D. F. Diao The contact mechanisms of a transfer layered surface during sliding wear of a Si 3 N 4 ball against the amorphous carbon film were investigated. In this study, amorphous carbon films were deposited by electron cyclotron resonance plasma sputtering technique. The dependence...

... and 60% reduction in carbide content had a more dominating effect on the contact fatigue resistance when compared with an order of magnitude improvement in the impact toughness of the HIPed Stellite 6 alloy. 24 02 2008 07 08 2008 04 12 2008 abrasion carbon casting chromium...

...Feodor M. Borodich; Leon M. Keer; Stephen J. Harris The abrasiveness of hard carbon-containing thin films such as diamond-like carbon (DLC) and boron carbide (nominally B 4 C ) towards steel is considered here. First, a remarkably simple experimentally observed power-law relationship between...

...Jayashree Bijwe; J. Indumathi; Bhabani K. Satapathy; Anup K. Ghosh A carbon fabric composite of Polyetherimide (PEI) was fabricated and studied for fretting wear behavior along with neat PEI. The operating parameters were load, temperature, amplitude and frequency of fretting. It was observed...

...W. Lu, Graduate Student; K. Komvopoulos, Professor The dependence of the nanotribological properties of ultrathin amorphous carbon (a-C) films, deposited on Si(100) substrates by radio frequency sputtering, on their nanomechanical properties was investigated using surface force microscopy...

...W. Lu, Graduate Student; K. Komvopoulos, Professor Fellow ASME The nanomechanical and nanotribological properties of 10-nm-thick amorphous carbon ( a -C) films and 100-nm-thick polycrystalline chromium (Cr) and titanium carbide (TiC) films were investigated using a surface force microscope (SFM...

...Yasunaga Mitsuya, Professor; Hedong Zhang; Sakiko Ishida A Michelson interferometer based on the Linnik microscope configuration has been constituted and applied to the measurement of lubricant spreading on diamond-like-carbon (DLC) surface. Performing image processing on the fringe patterns formed...

...Lihong Zhang Ambient drag experiments were carried out using Al 2 O 3 - TiC sliders and carbon-coated aluminum/magnesium substrate disks. Worn carbon of disks resulted in sub-micron particles that transferred to smears under frictional heating and mechanical shear force. Raman analysis found...

...P. M. McGuiggan; S. M. Hsu; W. Fong; D. Bogy; C. S. Bhatia The friction force as a function of humidity was measured between thin carbon films coated onto mica surfaces. The friction force was found to be proportional to the area of contact. The shear stress at 0 percent, 33 percent, and 100...

...Chao-Yuan Chen; Jianjun Wei; Walton Fong; David B. Bogy; C. Singh Bhatia Tribo-chemical studies of the head/disk interface (HDI) were conducted using hydrogenated CH x carbon disk samples coated with perfluoropolyether ZDOL lubricant. The studies involved drag tests with uncoated and carbon-coated...
