Wear investigation of elastically similar sliding bodies material

From the practical point of view to obtain the friction and wear characteristic of
materials used in machinery, various types of wear testing machines have been
developed and deployed. To obtain useful data for practical application, it is desirable
that the investigation is carried out by a full scale wear testing apparatus having
approximat.ely similar contact conditious. There are two parameters in the wear testing
machines, such as configuration of contact surface and form of the relative motion
between test specimens. Thus, in this report, the effect of unidirectional sliding friction
in linear sliding direction between contacting pair and friction obtained test results are
investigated. The reciprocating pin-on-flat experimental technique of similar
specimen's material was modified to obtain the test results desired. The microscopic
structures of the pin specimen were varied due to frictional and wear properties.
Pressure distribution using selected formula during normal condition and the wear
effect on the leading and trailing edge due to the movement of pin specimen were
varied due to the load and number of cycles applied. Comparison between theoretical
wear depth and experimental result been analyzed.
