“…The analysis of variance (ANOVA) results from Table 4 also revealed that these two parameters ( current and T-On ) and their interaction are significantly affecting the volume of a channel with p -values less than 0.05. 27 From the factorial plots, the volume of the channel was found to be higher at moderate value of discharge idle time, T-off (level 2: 36 µs). It is because if the idle time is too short the molten material could not be flushed away by the dielectric and gets re-solidified at the inter-electrode gap.…”

The aluminum alloy AA6061-4wt.% boron carbide (B4C) particulate metal matrix composites were fabricated by the stir casting method. The die-sinker electric discharge machining was performed to make the rectangular mini channels on these composites. The full factorial experimental design that consists of three input conditions, the current ( I), discharge duration ( T-on), and discharge idle time ( T-off) at three levels each (33 = 27 total runs), was used for experimentation. The volume, V, the taper, θ (along with the depth), the lateral overcut (along the width), and the difference in depth, Δ d (between total depth and depth up to the tapered profile) at entrance and exit cross-sectional profiles of the channel were considered as output responses. The θ, lateral overcut, and Δ d were calculated from the entrance and exit profiles which were obtained by extracting the data points of each channel with the help of an optical profile projector. The computer-aided geometric model was developed to estimate the volume. A set of optimum electric discharge machining parameter levels were identified for maximum V and a minimum of θ, lateral overcut, and Δ d. Analysis of variance was performed to identify the significant parameter and the contribution toward output responses. Results showed that the volume was found to be maximum at higher I (8 A) and lower T-On (25 µs) conditions. The taper was found to decrease with the increase in current but both lateral overcut and Δ d increased. Both I and T-On are found to be the significant parameters affecting both V and Δ d, whereas current is for θ and lateral overcut. In some cases, it was observed that there is a considerable difference in the θ and the lateral overcut values in the entrance and exit portions for the same channel. It is because of the randomly dispersed B4C particles which alter the material removal mechanism.

“…Results were measured as the weight loss after the wear. Samples of the size of 10 cm diameter and 30 cm height were prepared based on ASTM G99-05 standard at CITCO, Chandigarh [22]. The cross-sectional surface of the samples was mechanically rubbed using emery papers and velvet cloth.…”

In the present study, wear behavior of Al6061 hybrid composite having silicon carbide and red mud as the reinforcements have been studied. This hybrid composite was fabricated using the stir casting technique. Effect of variation of magnesium content, red mud content, aging time, red mud particle size, applied load, displacement and speed were studied. Scanning electron microscopy confirmed the fairly uniform distribution of the reinforcement particles and provided wear patterns of this composite. Energy dispersive spectroscopy showed different constituents present in this hybrid composite. Wear loss decreased with an increase in magnesium content and aging time while it decreased with an increase in red mud content up to 4% (wt%) and particle size up to 150 mesh (105 µm). Wear loss increased with an increase in load, sliding speed and sliding distance. Load and sliding distance have a significant effect on the wear loss. Optimum values for minimum weight loss were calculated and were confirmed by confirmation experiments. Load and sliding distance have been found to have significant effect on wear loss. So this fabricated composite can be utilized in various applications like in Marine frames, Aircraft and truck frames, Chemical equipment, aircraft landing mats etc.

“…In order to reduce pollution, numerous scholars have conducted a lot of research in the resource utilization of industrial waste and achieved some results. For example, red mud is currently used in magnesium phosphate cement [8,9], ultra-high-performance concrete [10,11], and envi-ronmental remediation agents [12,13] after treatment. However, many studies have shown that the particle size and admixture of industrial waste sludge can have a significant effect on the performance of cement mortar [14][15][16].…”

Five particle sizes and six dosages of polymerized aluminum chloride (PAC) residue were taken to prepare polymerized aluminum chloride residue cement mortar (PACRM). The compressive and flexural strengths were tested, and SEM analysis was performed. The results showed that the change pattern of strength of PAC waste residue mixed into cement mortar was similar to that of fly ash at the same substitution rate. However, the strength of PACRM decreased with the increase of substitution rate. The flexural and compressive strengths of PACRM reached their peak at all ages after replacing cement with PAC waste residue with particle size of 0-0.075 mm and 30% doping. Their strength ratios were greater than 62%. It does not contribute much to the early strength development of PACRM, but contributes more to the later strength development after the cement is replaced by PAC waste residue. PAC waste residue mainly acts as microaggregate and fills into the mortar pores at low substitution rate. The cracks of the matrix structure are filled by C-S-H, so the mortar structure is more dense and the material strength is enhanced. When the substitution rate increases, the water requirement of mortar increases, resulting in an uncompact structure. The internal pores increase after hardening, and the mortar strength decreases rapidly.
