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)
