Analysis of generated wear debris of brass during dry sliding

Abstract

Although a lot of studies were performed about wear debris, there is a lack of procedures that can identify and measure the size and size distribution of the generated debris. To find a more precise and innovate method characterizing wear debris size, average size, and size distribution measurements, the j image software program is applied as a consequence to sieving, optical microscope photography, and computer aided sorting processes. The wear investigates are carried out on a pin-on-disc test machine under dry sliding situations for the brass pins against steel disc type EN 31 under five different loads. The results demonstrate that the usage of the above-stated sequence of processes is a reliable technique that leads to obtaining more accurate results of the required measurements for all types of the generated debris.
