| description | Material properties are crucial during surface interaction in rolling contact as it
may affect friction and wear. The contact condition can be controlled by selection of
material of the mating surfaces based on the produced contact stress and the hardness. A
good selection of materials may increase the performance and the lifetime of any
mechanical components. Wear and plastic deformation are two critical mechanisms that
may lead to surface failure during rolling contact. In this work, the experiment is carried
out using online method where the surface scanning is carried out directly under the
Infinite Focus Microscopy (IFM). Four different materials are used to fabricate the roller
specimen, there are aluminium, brass, mild steel and stainless steel to produce different
contact condition. Surface asperities profile at initial and final condition is plotted to
evaluate the surface asperities deformation. The average roughness Ra from 0 cycle until
100 cycle is plotted and found can be used to indicate wear rate. The BAC parameter is
sufficient to present the ratio of asperities peak where high Rpk is obtained when the
surface asperites profile has high peaks. Based on surface roughness parameter and
asperities profile, aluminium which has the lowest hardness value has the highest surface
deformation followed by brass, mild steel and stainless steel that having lower hardness
respectively. The finding shows that material hardness has a significant effect on the
deformation rate compared to modulus of elasticity and contact pressure. The material
with higher hardness shows less deformation compared to the lower hardness material. |
