“…In the case of FGMs, again sliding velocity ( p = 0.002) and filler content ( p = 0.006) have significant contribution in the order of priority toward the specific wear rate but sliding distance ( p = 0.138) and normal load ( p = 0.346) have contribution of output performance (Table ). This trend of observations was also observed by other researchers for polymer‐based composite materials during sliding wear analysis . Analyzing the above contribution of interaction of different factors, it is evident that the interaction of sliding velocity/filler content ( p = 0.009) has most significant contribution, and it also played some role in the interaction of filler content/normal load ( p = 0.174), respectively.…”

The study aims for potential utilization of red mud (an industrial waste) to be utilized as a wear-resistant material.Investigations on mechanical and wear characteristics of red mud epoxy based homogeneous and their functionally graded materials (FGMs) developed with an intent of probable application in tribological systems are presented. The influence of significant operational parameters, material parameters, and their subsequent influences among themselves are explored. A specially designed experimental series is performed on a pin-on-disk machine with three different sliding velocities 105, 209, and 314 cm/s under three different loading conditions of 20, 30, and 40 N and compares the experimental results with the reported theoretical wear model. Artificial neural network approach is also applied to the wear data for subsequent validation. The comparative study indicates that although the homogeneous composites and FGMs exhibit relatively inferior mechanical properties, the sliding wear performance of the FGMs is better than homogeneous composites. It is also found that out of all synthesized composites FGMs exhibit the maximum impact strength and tensile modulus, which clearly indicates that the gradation achieved because the centrifugation technique enhances the crack arresting capability of the materials. The measured Young's moduli of homogeneous composites and FGMs were compared to standard theoretical prediction models. The measured moduli values showed good harmony with those predicted from Halpin-Tsai and Kerner models. Transmission electron microscopy microstructures confirm the continuous graded dispersion of red mud particles in the matrix. C 2015 Wiley Periodicals, Inc.

“…Mckellop [67] stated that increasing the surface roughness of ceramic surface resulted in higher wear of prosthetic joint. The significance of metal surface roughness for controlling the wear of acetal gear against a hard counterface even in real life operating conditions is confirmed [76]. …”

Coatings such as diamond-like carbon (DLC) and titanium nitride (TiN) are employed in joint implants due to their excellent tribological properties. Recently, graphite-like carbon (GLC) and tantalum (Ta) have been proven to have good potential as coating as they possess mechanical properties similar to bones—high hardness and high flexibility. The purpose of this systematic literature review is to summarize the coating techniques of these four materials in order to compare their mechanical properties and tribological outcomes. Eighteen studies published between January 2000 and February 2013 have met the inclusion criteria for this review. Details of their fabrication parameters, material and mechanical properties along with the tribological outcomes, such as friction and wear rate, were identified and are presented in a systematic way. Although experiment conditions varied, we conclude that Ta has the lowest wear rate compared to DLC, GLC and TiN because it has a lower wear rate with high contact pressure as well as higher hardness to elasticity ratio. However, a further tribology test is needed in an environment which replicates artificial joints to confirm the acceptability of these findings.

“…Short fiber reinforced polymers permit fabrication of complex shaped products economically using injection-molding process. Many research works have been performed on the issues related to the performance of polymer and polymer composite gears [1][2][3][4][5][6][7][8][9]. In those articles influence of reinforcement on the fatigue performance and wear resistance of polymer gears is well discussed.…”
