STUDY THE EFFECT OF PRODUCED TEMPERATURE DUE TO FRICTION ON THE BEHAVIOUR AND CHARACHERISTICS OF THE DRY SLIDING WEAR OF THE ACICULAR BAINITIC DUCTILE IRON

Abstract

ABSTRACT:- This research paper shows the effect of the rising temperature due to the friction between the mechanical parts which has an effect on the behaviour and characteristic of the dry sliding wear. Specimens of ductile iron are used in this research for this purpose under the effect of certain applied loads and sliding speeds. It has shown that, the mean temperature is increased with the sliding speed . This research has proved that , the average of the wear can have a high values under the temperature range (300-400)C and its maximum value can be obtained at the sliding speed (1.406) m/sec. The applied load on the ductile iron specimen can be seen in a linear relationship with the average of the wear in all sliding speeds while, at load of (40)N a maximum average wear can be obtained . This research also shows that, the friction factor is increased with the increasing of the surface temperature due the hardening of the graphite layer with the temperature rising.
