Abstract
The purpose of this study was to evaluate the wear resistance of tooling materials using impact abrasion testing. Materials tested are being used or are being considered for use in pattern and corebox construction. This study used 14 materials for evaluation. The materials were chosen on the basis of recommendations made by manufacturers and patterns shops. This study used the same procedure established in a study done in 1992 by Vondra to evaluate materials against a standard sample.
Of the materials tested three were included in the ceramics group. These materials demonstrated average wear resistance. The percent weight loss ranged from 1.290% to 2.325% over a twelve hour period of time. Two of the three materials demonstrated that they could achieve a weight loss under the acceptable standard of 1.6% established in a previous study done by Maier and Wallace. (1977)
The polyurethane elastomer group consisted of three materials. One material RP644 was tested twice. This was done to see what different curing times and temperatures have on the material. This group had an average weight loss ranging from . 9540% to 1.1816% over a twelve hour period. The relative low weight loss of this group suggests that it should be considered for use in pattern and corebox construction.
In addition to the nonmetallics there were five metallic materials evaluated. Among these was the benchmark material, Class 40 gray iron. All of the metallics performed as expected. The steels performed better than the gray iron, which tested better than the aluminum samples. These materials were chosen on the basis that they are being used as tooling materials and have not been tested previously.
