“…Investigation of the experimental outcomes uses signal to noise ratio to support the determination of the finest process design. This method is effectively used to study of dry sliding wear behavior of composites materials [10]. In this work, the "smaller the best" quality characteristics were taken to finding the minimum wear rate and coefficient of friction.…”

Al-7075 alloy-base matrix, reinforced with mixtures of silicon carbide (SiC) and boron carbide (B 4 C) particles, know as hybrid composites have been fabricated by stir casting technique (liquid metallurgy route) and optimized at different parameters like sliding speed, applied load, sliding time, and percentage of reinforcement by Taguchi method. The specimens were examined by Rockwell hardness test machine, Pin on Disc, Scanning Electron Microscope (SEM) and Optical Microscope. A plan of experiment generated through Taguchi's technique is used to conduct experiments based on L 27 orthogonal array. The developed ANOVA and the regression equations were used to find the optimum wear as well as coefficient of friction under the influence of sliding speed, applied load, sliding time and percentage of reinforcement. The dry sliding wear resistance was analyzed on the basis of "smaller the best". Finally, confirmation tests were carried out to verify the experimental results.

“…Scanning electron microscope (SEM) observations also indicated that homogeneous composites TiO 2 particles were peeled off from the matrix to form holes while in graded composite materials under same testing conditions, the TiO 2 particles remain quite intact to the matrix. In another study, Siddhartha et al [31] reported the tribological behaviour of cement kiln dust (CKD) particulate-reinforced homogeneous and their graded epoxy composites synthesized by simple mechanical stirring and vertical centrifugal casting techniques, respectively. Sliding wear tests were performed over a range of sliding velocities (105-314 cm/s), normal loads (20-40 N), filler contents (0-20 wt.%) and sliding distances (0.5-2 km) using a pin-on-disc machine.…”

The dry sliding wear characteristics of glass-epoxy (G-E), graphite-filled G-E and functionally graded graphite-filled G-E composites were investigated using pin-on-disc test rig. The specific wear rate was determined as a function of applied load, sliding velocity and sliding distance. The results revealed that the specific wear rate increases in all the tested composites with increasing wear parameter. But, the admirable wear resistance was obtained with functionally graded graphite-filled G-E composite. The scanning electron microscope studies of worn-out surfaces support the involved wear mechanisms and are well indicated in the worn-out surface features such as matrix wear, fibre exposure, fibre breakage, fibre and matrix deboning, microcracking, debris formation, fibre cracking and removal of fibres.

“…Higher wear volume loss has been recorded with increase in sliding velocity and the coefficients of friction showed an increasing trend with increase in load and sliding velocity. Siddhartha et al [5] have investigated titanium dioxide (TiO 2 ) reinforced epoxy functionally graded composites. They concluded that addition of TiO 2 particles into epoxy has a dramatic effect on the flexural strength tensile modulus, and impact strength in comparison 2 Advances in Tribology to homogeneous composites.…”

The mechanical properties and dry sliding wear behaviour of glass fabric reinforced epoxy (G-E) composite with varying weight percentage of silicon dioxide (SiO 2 ) filler have been studied in the present work. The influence of sliding distance, velocity, and applied normal load on dry sliding wear behaviour has been considered using Taguchi's L 9 orthogonal array. Addition of SiO 2 increased the density, hardness, flexural, and impact strengths of G-E composite. Results of dry sliding wear tests showed increasing wear volume with increase in sliding distance, load, and sliding velocity for G-E and SiO 2 filled G-E composites. Taguchi's results indicate that the sliding distance played a significant role followed by applied load, sliding velocity, and SiO 2 loading. Scanning electron micrographs of the worn surfaces of composite samples at different test parameters show smooth surface, microploughing, and fine grooves under low load and velocity. However, severe damage of matrix with debonding and fiber breakage was seen at high load and velocity especially in unfilled G-E composite.
