| Description |
The study of wear particles is useful in understanding the wear
processes prevailing in the contact zone, and can help in defining
the prevailing significant wear mechanism and the mechanics of
particle detachment. This paper describes a wear study carried out
under simulated plastic deformation conditions where coil type foil
wear particles were typically ob%erved both on the surface as well as
in the form of loose particles. It is proposed that such particles
could be formed as a result of accumulated residual stresses in the
wear particles. Based on the residual stress theory the diameters of
the coil type particle were estimated and then compared with those
measured through a scanning electron microscope. The contact
consisted of a pair of mild steel and EN 31 discs brought together at
the circumference. The conditions were simulated using a modified
Amsler friction and wear te~ting machine. The lower disc carried the
lubricant to the contact zone. Contact pressure of the order of 1.12
GN/m2 was obtained which is well above the yield point of the mild
steel. The wear particles were also examined by X-ray diffractionifor
the nature of deformation. Correlation between the estimated and
experimental value of diameter of wear particles was good and throws
light on the mechanism of such wear.
