Reciprocating wear tests of Al–Si/SiCp composites: A study of the effect of stroke length

Abstract

The aim of the work described here was to find evidence for the influence of stroke length on the reciprocating wear of aluminium matrix composites. For this purpose, two kinds of tests were performed: reciprocating ball-on-plane geometry experiments to apply stroke in the millimetre range, and fretting tests to study the strokes in the micrometer scale. The relationships between the dissipated energy and the wear volume were established to compare these two different scale tests. The results are discussed in terms of energy approach and of the comparison of the wear mechanisms observed on the wear scars resulting from both tests.

Evaluation of Mechanical, Microstructures and Wear Behaviours of Aluminium Alloy Reinforced with Mussel Shell Powder for Automobile Applications

“…% of MSP loading. The improvement of the hardness of the composites to the increased particle volume fraction, and increased strain energy at the periphery of particles dispersed in the matrix confirmed the previous studies [22] and [23].…”

Coated and uncoated reinforcements metal matrix composites characteristics and applications – A critical review

“…This technique is more cost-effective since it eliminates the fabrication stages and also the energy and time consumption. (Gomes et al, 2005) examined that, due to a supportive combination of cost-efficiency, hardness, and density, SiC and Al 2 O 3 are widely used among many ceramic materials Al-MMCs reinforced with these reinforcements, shows a substantial improvement in its strength, hardness, wear-resistance, and elastic modulus. (Ravichandran et al, 1992) discovered that the reason for alumina and other oxide particles like TiO 2 etc.…”

Enhancing the Mechanical and Reciprocating Wear Behavior of Functionally Graded A359 Aluminium Alloy Through Heat Treatment

“…Using a pin on flat tribometer setup (DUCOM) (Fig. 2), linear reciprocating wear tests are performed on samples prepared based on the recommendations mentioned in ASTM G133 standard [15,22]. The experimental parameters are also defined as per the standards.…”

“…10). This is attributed to the spheroidised eutectic silicon formation in heat treated condition and the sound casts produced under the sway of centrifugal action with a smaller number of casting defects [15]. This increases the hardenability of the heat treated samples, which simultaneously decreases the material removal rate.…”

“…The wear behavior of Al-Si alloy depends mostly on process parameters such as load, frequency, sliding distance, mechanical properties, composition and interfacial conditions [13,14]. Gomes et al and Rajeev et al confirms that under optimum conditions, Al-Si alloys frictional force and wear rate increases with increase in load [15,16] whereas under the influence of higher sliding speeds, a non-linear decrease in wear properties are observed [17,18]. As steel is the widely used material and aluminium is the successor, the aluminium-steel tribo-pair is preferred for studying wear [19].…”
