“…Owing to its lower bonding strength, fly ash particles can easily pull out from the matrix, leading to an increase in wear rate. Mewar and Mer 15 reported that at the higher speed of abrasion, the energy involved in eroding the material surface does not get time to dissipate and the major part of the energy is utilised in causing abrasion resulting in higher wear rate.…”

“…An increase in load raises the imparted energy and changes the wear regime from mild wear to severe wear. 8,15 An increase in sliding speed increased the wear rate of the aluminium fly ash composites (Fig. 3b).…”

“…The specific wear rate of the composites against sand grains remains constant due to formation of graphite film. 15–17 The abrasive wear rate of the composite materials increased with increase in abrasive size, applied load and sliding distance. 18 The wear behaviour of Al/alumina composites while sliding against brake disc material experienced a combination of adhesive, abrasive and fatigue wear.…”

Aluminium alloy (Al/3.25Cu/8.5Si) composites reinforced with fly ash particles of three different size ranges (53-75 mm, 75-103 mm and 103-125 mm) in 3, 6 and 9 wt-% were fabricated using liquid metallurgy technique. Pin on disc abrasive wear tests were carried against the disc surface fixed with SiC emery paper (120 grades). A mathematical model was developed to predict the abrasive wear and coefficient of friction of the composites. Analysis of variance technique was used to check the validity of the developed model. Composites reinforced with coarse fly ash particles exhibited better abrasive wear resistance than those reinforced with fine fly ash particles. Abrasive wear in composites with fine fly ash particles is a combination of adhesive wear and abrasive wear. Larger fly ash particles present in composites gets fractured into fine particles and entrapped between the composite pin and the disc, thereby decreasing the wear rate. Worn surfaces of the pins were then analysed using scanning electron microscopy to study the wear mechanisms of the composites. The abrasive wear was optimised using desirability based multiobjective optimisation technique.

“…The abrasion wear mass loss was reduced for the aluminium-graphite composite comparing with pure aluminium and aluminium magnesium alloys [12]. Wear rate of Al-Gr composites tend to decrease with increasing the graphite content and sliding velocity at constsnt load due to the formation of graphite film on the surface.…”

In recent year's aluminium and aluminium alloys are widely used in automotive industries. These are light (density of about 2.7 g/cm3), having good malleability and formability, high corrosion resistance and high electrical and thermal conductivity. Metal matrix composites (MMCs) are being employed in industrial applications since they have high specific strength, stiffness, and good wear properties. Due to their favourable properties, composite materials with reinforcements are used in many industries. With the aim to additionally improve some of their properties, especially their tribological properties, several solid lubricants are used in the process of composite production. This paper gives an overview of investigations and possibilities of solid lubricant particles (such as graphite) applying as complementary material, mainly for aluminium base composites that are nowadays common in use in automotive and aeronautics industry.
