Microstructural effects in abrasive wear: Final report for period September 15, 1981--March 14, 1986
This report summarizes research performed on abrasion of metallic alloys. The work was designed to improve our understanding of the factors affecting abrasion rates in two-phase alloys containing large, hard second-phase particles (SPPs) such as carbides, since this class of alloys generally has very high abrasion resistance owing to the presence of such carbides. The project was divided into sections dealing with material removal in the carbide and matrix phases. The materials studied included Stellite and high Cr-Mo white cast irons and a set of specially prepared model alloys containing one of six types of artificial SPPs dispersed in a sintered matrix of pure Cu. Scratch tests were employed to simulate abrasion mechanisms, and specially designed scratch test systems were fabricated to permit scratch testing in-situ in the scanning electron microscope (SEM) and to permit scratches to be made at fixed depths of cut rather than fixed loads. Three types of abrasion tests were employed; a dry-sand rubber wheel abrasion test; a low-speed ''gouging'' abrasion test employing a special low-speed Al/sub 2/O/sub 3/ grinding wheel; and a pin-on-disc abrasion test using abrasive paper. Abrasive type and size was varied in the rubber wheel and the pin-on-disc tests. 27 refs., 10 figs., 5 tabs.
