Friction and wear behaviour of 18 polymers in contact with steel in environments of air and water [PDF]

, 1991
18 polymers were characterized with respect to their friction and wear behaviour in contact with steel in environments of air and water. These were six unfilled materials, i.e. polyamide 66 (PA 66), polyoxymethylene (POM), polyethyleneterephthalate (PETP)
