INVESTIGATION OF FRICTION CHARACTERISTICS AND WEAR RESISTANCE OF ACRYLIC PLASTICS FOR SLIDE BEARINGS,
Abstract
Acrylic plastics can be widely used in the form of thin coatings to reduce the wear of friction parts such as bushings, bearings, etc. A high-quality plastic coating is attained by pouring a heated solution of the plastic to a thickness of 0.3-0.5 mm over a finely finished and cleaned metal base. Because acrylic plastics harden at room temperature and lose good bonding characteristics in 10-15 min, the solution prepared is used immediately. To determine the friction and wear resistance, the plastics were tested on a friction machine and under actual operating conditions on an automobile assembly conveyor. Although lubrication improved operating conditions, a limiting temperature is reached at which the plastics break down as though they had not been lubricated. Therefore, a copious and continuous supply of lubricant is needed to keep friction to a minimum and to improve wear resistance. (Author)
