“…Inspection of Figure (b) reveals that there has been very little deformation on the surface of the steel but rather some of the pin's material has been deposited onto the steel's surface. This depositing of polymer to the surface of the steel agrees with research conducted by Vanarotti et al ., where microscopy images of the worn steel surface showed debris accumulation.…”

“…This behavior agree with research conducted by Ho et al, who stated that the nature of the stresses in postwear testing metal matrix composites against a hardened steel disk was always compressive. The magnitude of residual stresses encountered in previous research produced a large range of values with the lowest measuring −20 MPa and the highest, −180 MPa for varying load from 30 N to 70 N. Here the range is much smaller (−14 MPa to −30 MPa) due to the smaller values of loads used in this experiment.…”

Some properties of polymers can be improved through the incorporation of carbon and glass fibers into the polymer matrix. In this research, the wear resistance of two polymer composites CF‐polyether ether ketone (PEEK) and GF‐PEEK were compared with the virgin PEEK. The wear resistance was assessed by Pin on Disk tests performed using a range of reinforced polymer pins tested against a steel disk. The influence of load, sliding velocity, counter‐surface hardness, and reinforcement concentration and type, on the specific wear rate was investigated. The materials were chosen to simulate the wear experienced between a polymeric anti‐extrusion ring and a steel sealing surface utilized within valves in the oil and gas industry. The average mass loss was recorded and an analysis of the variance (ANOVA) carried out to investigate the contribution of each parameter on specific wear rate. Results showed that weight percentage reinforcement and type of reinforcement material were primary contributors toward specific wear rate, with a contribution of ~70%. Secondary contributors were sliding speed (~14%) and load and steel hardness (~12%). Following the wear tests, residual stress measurements were conducted on polymer reinforced with carbon fiber. It was found that compressive residual stresses existed, and that their magnitude increased with increasing load. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 47587.

“…Enhancement in strength is associated with restrictions on the pinning (14) by fine dispersed particles. When the particle size increases beyond a critical value, dislocations shear throug the particles and the resultant enhanced mobility leads to decreases in strength (14)(15). The reduction in strength has been found to vary with the nature of particle dispersed in the matrix.…”

Metal matrix composites of aluminium alloy with silicon carbide reinforcement are useful in aerospace, automobile and general engineering industries because of their favourable microstructure and mechanical behavior. Composites of aluminium alloy LM12 and silicon carbide were fabricated by using stir casting technique. In hardness and tensile test conducted, a significant improvement in material strength is observed in aluminium alloy LM12 metal matrix composite as compared to the alloy without silicon carbide addition. Cast base metal and its composites were found to fail predominantly in brittle mode during the tension test. During, casting silicon carbide, the content composite was fixed at 10 and 15 Weight, after casting a microscopic examination is conducted, and witnessed a uniform distribution of silicon carbide in aluminium alloy LM12. Casting technique and characterization of aluminium alloy LM 12 and silicon carbide metal matrix composite (MMC) are described in the present paper.

“…Even though various methods are in practice for the production of MMC's [1][2][3][4][5][6][7]. Liquid metal stir casting method proved to be a better method in achieving wettability and homogeneous dispersion of reinforced materials [8,9,12,16]. In this direction earlier research work of krez and so et al made concluding remarks that, wetting agents and wetting angle plays vital role in producing quality composites [10,11].…”
