Influence of Succinimide Dispersants on Film Formation, Friction and Antiwear Properties of Zinc Dialkyl Dithiophosphate [PDF]
, 2012 ZDDP (zinc dialkyldithiophosphate) is arguably the most successful antiwear additive ever employed in crankcase engine lubricants. It was originally used as an antioxidant and shortly afterwards recognized for its antiwear and extreme pressure ...

Running-in wear modeling of honed surface for combustion engine cylinder liners [PDF]
, 2013 The texture change during running-in alters the performance and efficiency of a tribo-mechanical system. During mass production of cylinder liners, a final finishing stage known as ‘‘plateau honing’’ is commonly added to reduce the running-in wear ...

Lubrication properties of nylon mixed with lubricants.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987 Plastics are used widely as sliding parts. In order to investigate the effect of the varied lubricants mixed in the nylon rollers, experimental equipment was designed and manufactured. In the experiment on the friction of the nylon roller, a nylon roller was rotated contacting with a steel roller in the same direction.
