Effect of Metallic-Coating Properties on the Tribology of Coated and Oil-Lubricated Ceramics

PDF Version Also Available for Download.

Description

Friction and wear behavior was determined for zirconia ceramics lubricated with solid coatings (Ag, Au, and Nb) deposited by ion-beam-assisted-deposition (IBAD) techniques, and a polyol-ester-based synthetic oil. Although the use of soft Ag and Au coatings as solid lubricants in conjunction with the synthetic oil significantly reduced the friction and wear under boundary lubrication at temperatures up to 250[degrees]C, these films had poor durability. In contrast, the Nb coating was more durable (in terms of chemical reactivity and adhesion during the tribo-tests) than were the Ag or Au films. However, the friction and wear behavior of the Nb-coated zirconia was … continued below
