Physical properties and wear behaviour of aluminium matrix composite reinforced with palm shell activated carbon (PSAC)

Abstract

This study was aimed to investigate the influence of reinforcement content on the physical properties and wear behaviour of composite pure aluminium reinforced with palm shell activated carbon (PSAC). Pure aluminium was reinforced with 0 %, 5 %, 10 %, 15 % and 20 % by weight of PSAC and then compacted at 200 MPa followed by sintering at 500 • C for 2 h. Quantitative analysis on dry sliding wear behaviour was investigated by means of pin-on-disc wear testing machine. Wear rates of the composite were determined at fixed applied load (10 N) and sliding velocity (150 rpm). Optical micrograph showed that an increasing PSAC content had resulted in increasing of pores in the composites. The hardness and density decreased with the addition of PSAC content. They were reduced drastically with the amount of PSAC content more than 10 wt.%. The cumulative wear rate of the specimens was observed decreased with the amount of PSAC content less than 10 wt.% PSAC and increased with PSAC content more than 10 wt.%. The optimum content of PSAC was found to be 10 wt.% in order to achieve optimum wear resistance.

Production of Aluminum Matrix Composite Material by Active Carbon Additive

“…It was synthesized and applied to remove sulphide ions from water [10]. Wear behavior and physical properties of aluminum have been discussed along with palm shell activated carbon [11]. We utilized reinforcement in particulate form, which suits the composite preparation technique, and reinforcement was nothing other than activated carbon.…”

Effect of Reinforcememt Particles Preheating on Mechanical and Microstructural Properties of Amc

“…It was found that the use of palm kernel shell char at the disperse phase yielded identical result with coconut shell char. [16] studied the physical properties and microstructure of pure aluminium reinforced with palm shell activated carbon. Various mix percentage were used and powder metallurgy technique employed for the compaction of the composites.…”

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

“…Recently, many research works have been conducted to determine ways to decrease friction and wear using other types of composite materials, lubricants and even coatings for applications in tribology (Findik, 2014; Li et al , 2011; Bakry et al , 2013; Kato, 2000; Ghassemiah, 2011; Yoon et al , 1997; Abdollah et al , 2010, 2012; Zhou et al , 2005; Abdollah et al , 2014). Previous studies found that carbon-based materials can perform as a self-lubricating material when strengthened with different materials (Baradeswaran and Perumal, 2014; Sharma et al , 1998; Zhai et al , 2014; Gomes et al , 2001; Baradeswaran and Perumal, 2014; Kumar and Wani, 2017; Zamri and Shamsul, 2011; Zamri et al , 2010; Mat Tahir et al , 2016; Chua et al , 2014).…”
