This research work was undertaken to study the effect of dry sliding wear process parameters such as load, time, and sliding velocity on the wear rate and coefficient of friction of AA8011 with 8 wt.% fly-ash composites. The response surface methodology was used to determine the most important criteria to maximize the wear rate and minimize the coefficient of friction. The experimental procedure was designed based on second-order rotatable central composite design. The optimization studies were carried out on dry sliding wear process parameter with multi-response characteristics, including the wear rate, coefficient of friction, based on multi-criteria decision-making using the TOPSIS approach. Sensitivity analysis was used to identify the important criteria and classify them by their order of importance in model validation. A confirmation test was carried out to validate the results, and the obtained optimal parameter levels were found to be very close to an ideal solution.

“…The star points were at the face-centre of the cube portion that corresponds to an α value of 1 and this sort of design was usually known as the "face-centred CCD." The tests were conducted using stipulated conditions in keeping with the face-centred CCD with 20 experimental observations at three independent input variables [15][16][17][18].…”

“…This controlling of wear should be considered cautiously from the idea of choosing the alloy composition, reinforcement and additionally the process techniques. The incorporation of hard reinforcement segments, particulates, fibres and whiskers has been capable of these composites through smart tribological characteristics [2,8,[12][13][14][15][16][17][18].…”

The current research work is focused on fabrication of Aluminium Alloy 8011 with 4% fly ash composite (AA8011-4% FA) by using the stir casting method. Wear behaviour and description of the composite are evaluated in different process parameters by using a pin-on-disc at room temperature. Fly ash (FA) in the range of (4 wt. %, average micron size 10-30 μm) is included into the matrix, and its sensitivity analysis is investigated. Three level of Central Composite Design model is developed by using Response Surface Methodology equation with different process parameters via load, time and sliding velocity are separate in the range of (5-15 N), (5-15 min) and (1.5-4.5 m/s) respectively. The surface plot shows that wear rate increases with increasing load, time and sliding velocity. A sensitivity analysis is also carried out and compared with the relative impact of input parameters on wear behaviour in order to verify the measurement errors on the values of the uncertainty in estimated parameters of three inputs such as normal load, time and sliding velocity on wear rate (WR) and coefficient of friction (COF). The result shows that normal load is more sensitive than the other parameters. The variation of load causes more changes in wear rate.

“…The results concluded that the wear rate increases with an increase in load, time and sliding velocity. Magibalan et al 8 concluded that a three-level central composite design experiment was developed successfully. The regression results showed that the developed model performed well in relating the wear process parameters and predicted the wear behaviour of the composite.…”

In this article, a new metal–matrix composite was developed with fly ash (an industrial waste from petroleum industries) as reinforcement and aluminium metal (A357) as a matrix by squeeze casting technique. This study was concentrated on the processing of the composites with different weight percentage ranging from 0 to 10 wt.% in a step of 2.5 each and also reported the erosion wear behaviour. Solid particle erosion of A357/fly ash composites was carried out with four velocities (48, 70, 82 and 109 m/s), at impact angles (30°, 45°, 60° and 90°), with silica as an abrasive particle at ambient temperature. The eroded surfaces were analysed by scanning electron microscopy. The results revealed that the impact velocity and impingement angle both affected the erosion wear behaviour of the composites. The erosion rate rises with an increase in impact velocity, irrespective of the change in impingement angle and weight percentage of the fly ash. The erosion mechanism studied for the composites is microploughing and microcutting.
