The Distribution of Zinc in Low-Friction ZDDP Tribofilm on Iron Oxide
Tribology Online, 2009 To develop a low-friction and low-wear tribo-system for engine components, the authors have been studying the ZDDP tribofilm formed on iron oxide. Tribotests on iron-oxide / steel sliding pairs were performed in PAO with 1 mass% ZDDP.

The preparation of double-walled carbon nanotube/Cu composites by spark plasma sintering, and their hardness and friction properties [PDF]
, 2011 Double-walled carbon nanotube (DWCNT)/copper composite powders were prepared by a rapid route involving freeze-drying without oxidative acidic treatment or ball-milling. The DWCNTs are not damaged and are homogeneously dispersed in the matrix.
