ABSTRACT:
Apparatus for testing abrasive wear on a surface of a sample. Flowable abrasive material is fed from a barrel against the surface. The sample is mounted reciprocally in the direction of feeding of the material, and urged by a force opposing that of the material thereon. The rate of feeding is controlled to maintain a gap between the end of the barrel and the sample so that the material flows continuously through the gap.
