Frictional wear stability mechanisms of an activated carbon composite derived from palm kernel by phase transformation study

Abstract

Purpose The purpose of this paper is to investigate the mechanisms of frictional wear stability of an activated carbon composite derived from palm kernel using phase transformation study. Design/methodology/approach The unlubricated sliding test was executed using a ball-on-disc tribometer at different loads with a constant speed, sliding distance and temperature. Findings Results of this paper suggest that stability of friction and wear of the test materials are primarily due to the phase transformation of the composite surface layer. Research limitations/implications However, the effectiveness of the transfer layer as a medium for low friction and wear is only limited at certain applied loads. Originality/value This is the first study, to the authors’ knowledge, to find out the mechanisms of low frictional wear properties of an activated carbon composite derived from palm kernel using phase transformation study.

Tribological performance of the graphene synthesized from fruit cover plastic waste and oil palm fiber using a CVD method

“…Various efforts have been made to eliminate or at least minimize friction losses such as introducing lubrication and its additives (Abdullah et al , 2016; Abdullah et al , 2014), development of new materials (Mahmud et al , 2019; Mahmud et al , 2017; Mat Tahir et al , 2016; Mat Tahir et al , 2015; Chua et al , 2014; Mustafa et al , 2014) and surface modifications (Amiruddin et al , 2019; Mohmad et al , 2017; Abdollah et al , 2013; Abdollah et al , 2011).…”

Influence of contact pressure and sliding speed dependence on the tribological characteristics of an activated carbon-epoxy composite derived from palm kernel under dry sliding conditions

“…However, when the contact pressure increases to the critical limit, the friction coefficient and wear rate rise drastically owing to the critical surface energy. This could be explained by the fact that the frictional heat raises the temperature of the friction surfaces, which leads to a reduction in the material strength and will eventually result in surface softening of the polymer composite or a decreased hardness of the composite, as discussed in our previous publication [29]. As for the sliding speed, both the friction coefficient and wear rate increase first and thereafter decrease at a higher speed of 500 rpm.…”

Effect of hydrogen on graphene growth from solid waste products by chemical vapour deposition: friction coefficient properties

“…The modification of surfaces includes surface treatments, textures and coatings (Bressan and Daros, 2008;Singh et al, 2011;Abdollah et al, 2012;Batzill, 2012;Findik, 2014;Mohmad et al, 2017;Saiful Badri et al, 2017). Allotropes of carbon, especially activated carbon, graphite and carbon nano-tubes, have been recorded as excellent anti-friction and wear materials (Fontaine et al, 2001;Brostow et al, 2010;Zamri and Shamsul, 2011;Prabu et al, 2012;Nirmal et al, 2015;Mat Tahir et al, 2016;Mahmud et al, 2017;Wang et al, 2017).…”
