EVALUATION OF SKID ABRASION RESISTANT MATERIALS.
Abstract
This program was conducted in an attempt to eliminate costly replacement of equipment platforms and runners subjected to skidding abrasion on concrete surfaces. It was desired to determine which of the twelve materials investigated (including eight metals and four non-metals) would be most suitable for use as wearing pads to be attached to the bottom of platform runners. The samples were subjected to drag runs of 50, 100, 200, and 500 feet. Runs were made on a concrete surface at surface pressures of 33 and 119 psi and drag speeds of 5 and 15 mph. The forces required to initiate and maintain motion of the different materials on the concrete surface were also measured. Finally, the relative magnitude of sparking among the different materials was determined. On the basis of the test results, Haynes-Stellite Alloy No. 1 was found to have the best wear resistance of the twelve materials tested. The relative sparking of this alloy was slight. (Author)
