TL;DR: In this paper, an attempt has been made to use CCLW as reinforcement with aluminium and the parameters of the friction stir process (FSP) are optimized by the Box-Behnken Design.
Abstract: Nowadays, there is a lot of environmental pollution due to the wastes generated by the industries. In particular, the waste generated by leather industries produces more environmental pollution. Chrome containing leather waste (CCLW) also causes a lot of environmental pollution. In this study, an attempt has been made to use CCLW as reinforcement with aluminium. Collagen powder was extracted from CCLW. Extracted collagen powder was used to develop aluminium based composite after ball-milling with alumina particles. The parameters of the friction stir process (FSP) are optimized by the Box-Behnken Design. The optimum combination of FSP parameters was found to be the number of tool pass of 1, tool rotational speed of 965.20 rpm and transverse speed of 23.69 mm/min. Tensile strength and hardness were found to be 162.89 MPa and 53.24 BHN, respectively at an optimum combination of FSP parameters. Uniform distribution of reinforcement particles has been also observed for the composite developed at an optimum combination of FSP parameters. Results showed that tensile strength and hardness of composite were enhanced by about 20.65 % and 23.81 % respectively with respect to the base material.

Abstract: In the present study, an attempt has been made to utilize spent alumina catalyst (SAC) waste as well as grinding sludge (GS) waste in the development of aluminum-based composite material. Nano-CuO particles have been added to the Al/SAC/GS composite to further enhance the mechanical properties of composite material. The microstructure of the developed composite by the stir casting technique showed the uniform distribution of the reinforcement particles. Results showed that tensile strength, hardness, and compressive strength of composite material improved by about 21.39%, 34.20%, and 20.73%, respectively, after adding the 4.5% SAC, 4.5% GS, and 1.5% nano-CuO in the aluminum alloy. However, the toughness of the composite material is decreased with respect to the aluminum alloy after adding the reinforcement particles. XRD of the composite material shows the presence of Al, Al2O3, Fe2O3, SiO2, and CuO phases. The presence of these hard phases may be responsible for enhancing the tensile strength, hardness, and compressive strength of composite material. Corrosion weight loss and thermal expansion of the developed composite have been also investigated to identify the SAC, GS, and nano-CuO addition to the aluminum alloy.

Abstract: In the concept of reuse and recycling, the waste alumina spent catalyst from the oil refineries is used as a reinforcement in aluminum composites. For this purpose, aluminum composites with the addition of nano SiC/Spent catalyst were fabricated using the stir casting process. The composites were prepared by reinforcing pure aluminum with 10 wt%spent catalyst and varying the nano SiC by 0.5, 1, 1.5, and 2 wt% respectively. The mechanical and microstructural properties of produced composites were then examined. The microstructure reveals that the nano SiC and spent catalyst were distributed uniformly in the pure aluminum matrix. The mechanical properties of fabricated composites were compared to pure aluminum. The fabricated aluminum compositesAl + 10 wt% Spent Catalyst + 1.5 wt% nano SiC demonstrates a maximum increase in hardness 99.80 HRB, tensile and compressive strength UTS = 134.53 MPa, UCS = 226 MPa compared to pure aluminum. As a result, the addition of different percentages of nano SiC / Spent catalyst to pure aluminum results in higher mechanical strength compared to the composite without reinforcement. • Aluminum composites with the reinforcement nano SiC and spent catalyst were fabricated using the stir casting technique. • The reinforcement nano SiC and spent catalyst showed a major impact on the mechanical properties of pure aluminum. • Addition of nano SiC and spent catalyst reinforcement increased the hardness, tensile and compressive strength of composites.
