The Influence of Intermittent Friction on Wear Phenomena of Plain Carbon Steel

Abstract

The influence of intermittent friction on wear phenomena of plain carbon steel (S33C) was investigated using high frequency induction hardened steel (S45C) as standard test piece.
The test was performed by means of rolling friction method having 15% slip without any lubricants, and in addition to the comparison of wear loss, wear particles and sliding surface were analized by X-ray diffraction method.
Results obtained are as follows.
1) Wear loss increases as the intermittent frequency and stopping time increase.This is due to that oxide produced on sliding surface is not sufficient.
2) Hardened steel have a good wear resistibility to intermittent friction and with increasing hardness the proportion of αFe₂O₃ in wear particles increases.
3) Under a small load there is little difference of wear loss for intermittent and continuous friction.
4) Intermittent friction causes a big plastic deformation on sliding surface.
