“…From Figure 5, the initial corrosion rate of the alloy increased from 0.0267 to 0.1644 mpy with the addition of 10 wt% SPFA after 24 h exposure in 0.5 M HCl acid at 303 K. Similarly, the corrosion rate of the alloy increased accordingly with the addition of 10 wt% SPFA from 0.0425 to 0.1947 mpy, 0.0567 to 0.2293 mpy, 0.0723 to 0.2500 mpy, and 0.0904 to 0.2787 mpy for 48, 72, 96, and 120 h exposure in 0.5 M HCl at 303 K. The same trend in increasing corrosion rate was recorded in 1.0 and 1.5 M HCl acid solution across temperatures of 303–333 K with increased content of SPFA as shown in Table A1 (Appendix). A similar increase in corrosion trends was observed previously with the addition of rice husk ash (Nithyanandhan et al. , 2020).…”

PurposeThe conflicting results on the corrosion characteristics of aluminium matrix composites reinforced with agrarian waste have stimulated an investigation on the hardness and corrosion rate of sugar palm fibre ash (SPFA) reinforced LM26 Al/alloy composite by varying the SPFA from 0 to 10 wt% in an interval of 2 wt%. This paper aims to discuss the aforementioned issue.Design/methodology/approachThe composites were produced via stir-casting and the hardness was determined using a Vickers hardness testing machine, corrosion rate was examined through the weight loss method by immersion in 0.5, 1.0 and 1.5 M hydrochloric acid (HCl) at temperatures of 303, 318, and 333 K for the maximum duration of 120 h. The morphological study was conducted using a scanning electron microscope (SEM) on the samples before and after immersion in HCl.FindingsThe incorporation of SPFA improved the hardness of the alloy from 58.22 to 93.62 VH after 10 wt% addition. The corrosion rate increases with increased content of SPFA, the concentration of HCl and temperature. The least corrosion rate of 0.0272 mpy was observed for the LM26 Al alloy in 0.5 M after 24 h while the highest corrosion rate of 0.8511 mpy was recorded for LM26 Al/10 wt% SPFA in 1.5 M HCl acid after 120 h. The SEM image of corroded samples revealed an increased number of pits with increased SPFA content.Research limitations/implicationsThe work is limited to SPFA up to 10 wt% as reinforcement in LM26 Al alloy, the use of HCl as corrosion medium, temperatures in the range of 303–333 K, and a weight loss method were used to evaluate the corrosion rate.Originality/valueThe corrosion rate was determined for LM26 Al/SPFA composites with various amounts of SPFA in 0.5, 1.0 and 1.5 M HCl at 303, 318 and 333 K and compared with the matrix alloy.

This work critiques an examination method to investigate the corrosion characteristic of composite materials with guide of Aluminium oxide and chicken bone ash as reinforcements. The weight percentage of aluminium oxide are 6%, 5%, 4%, 3% and 2% and Chicken Bone Ash are2%, 3%, 4%, 5% and 6% have been covered for this investigation. This composite casting method became made with the help of the stir casting method. The “Aluminium chloride” solution is used to examine the detail corrosion behaviour of the metal matrix composite by using of the immersion test.The result of this research work produce the corrosion rate would be decreased with increase of the weight percentage of Reinforcements. This work concluded that the estimation of rate of corrosion free with increment in maximum weight percent of hybrid composites.
