Abstract

The primary goal of this study is to evaluate the surface roughness of holes drilled in recycled AA6061 Alloy with recycled AA6061 alloy reinforced with novel Magnesium oxide ceramic strengthening particulates. Magnesium oxide ceramic particles of particle size < 50 nm were used as reinforcement particles, and recycled AA6061 alloys were used as matrix materials. To obtain uniform distribution of reinforcement in matrix materials, a stir cast method was used at a melting temperature of 720 °C and stirring speed of 500 rpm. Two groups of recycled AA6061 alloy and composite were manufactured. To analyze the surface roughness a drill was made on synthesized hybrid composites with a drill diameter of 8 mm at a spindle speed of 1000 rpm. The surface roughness of the novel SiO2 reinforced recycled AA6061 alloy was analyzed and compared with recycled AA6061/MgO alloy composites. Observation shows that a significance value of p = 0.000 (2-tailed) was obtained and found it was less than (p < 0.05) exemplifying that there are variances among the two clusters is statistically significant. Within the limits of the current investigation, it was found that when the proportion of nano reinforcement surface areas between the intermixtures was increased the surface roughness of nano magnesium oxide reinforced recycled AA6061 alloy composites was also significantly improved from 28% to 22.36%.
