Wear of Polymers in the Pin-on-Disc Configuration, APR 1984
Authors:  B. J. Briscoe; T. A. Stolarski; AMERICAN CHEMICAL SOCIETY WASHINGTON DC
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.A common simulation technique which is used to evaluate the wear of polymers is to slide the polymer, usually in the form of a pin, over the surface of a rotating disc. There are two obvious configurations. The pin may be loaded (along its major axis) either in a direction normal to or parallel with the axis of rotation. Hence the contact area is produced on the edge or the ...
