“…From the main effects plot, it is perceived that applied load has a significant influence on wear, followed by sliding speed and sliding distance. Similar results were obtained by Nayak et al [31]. In evaluating the result at the most favorable circumstance, the factors responsible for the significant contributions are incorporated.…”

Two-body abrasive wear behavior of glass fabric reinforced (GC) epoxy and titanium dioxide (TiO2) filled composites have been conducted out by using a tribo test machine. GC and TiO2 filled GC composites were produced by the hand layup technique. The mechanical performances of the fabricated composites were calculated as per ASTM standards. Three different weight percentages were mixed with the polymer to develop the mechanical and abrasive wear features of the composites. Evaluation Based on Distance from Average Solution (EDAS), a multi-criteria decision technique is applied to find the best filler content. Based on the output, 2wt% TiO2 filler gave the best result. Abrasive wear tests were used to compare GC and TiO2 filled GC composites. The abrasion wear mechanisms of the unfilled and TiO2 filled composites have also been studied by scanning electron microscopy. The outcome of the paper suggests the correct proportion of filler required for the resin in order to improve the wear resistance of the filled composites. Taguchi combined with Multi-Criteria Decision Method (MCDM) is used to identify the better performance of the TiO2 filled epoxy composites.

Purpose Aluminium and its alloys are the most preferred material in aerospace and automotive industries because of their high strength-to-weight ratio. However, these alloys are found to be low wear resistance. Hence, the incorporation of ceramic particles with the aluminium alloy may be enhanced the mechanical and tribological properties. The purpose of this study is to optimize the specific wear rate and friction coefficient of titanium dioxide (TiO2) reinforced AA7075 matrix composites. The four wear control factors are considered, i.e. reinforcement (Wt.%), applied load (N), sliding velocity (m/s) and sliding distance (m). Design/methodology/approach The composites were fabricated through stir casting route with varying weight percentages (0, 5, 10 and 15 Wt.%) of TiO2 particulates. The mechanical properties of the composites were studied. The specific wear rate and friction coefficient of the newly prepared composites was determined by using a pin-on-disc apparatus under dry sliding conditions. Experiments were planned as per Taguchi’s L16 orthogonal design. Signal-to-noise ratio analysis was used to find the optimal combination of parameters. Findings The mechanical properties such as yield strength, tensile strength and hardness of the composites significantly improved with the addition of TiO2 particles. The analysis of variance result shows that the applied load and reinforcement Wt.% are the most influencing parameters on specific wear rate and friction coefficient during dry sliding conditions. The scanning electron microscope morphology of the worn surface shows that TiO2 particles protect the matrix from more removal of material at all conditions. Originality/value This paper provides a solution for optimal parameters on specific wear rate and friction coefficient of aluminium matrix composites (AMCs) using Taguchi methodology. The obtained results are useful in improving the wear resistance of the AA7075-TiO2 composites.

“…Recently, many works have been done to improve the tribological properties of self-lubricating composites (Bastwros, et al 4 commercially known as C72900 alloy, can also be used as the tribo-material to make high-performance bearings for aerospace, roller cone rock bit and heavy duty mobile industrial equipment due to its high strength, high hardness and exceptional bearing properties (Kar,et al (14); Cribb,et al (15)). A lot of research have been done to investigate the tribological properties of copper-graphite composites (Cui,et al (16); Nayak et al (17); Rajkumar,et al (18)). …”

This paper provides an in-depth investigation into the formation of the mechanical mixed layer (MML) and its role in Cu-15Ni-8Sn/graphite composites. Wear tests were conducted at room temperature using a ring-block configuration with the applied load of 50 N and sliding speed of 0.42 m/s. SEM, EDS and XPS were performed to analyze the worn surfaces and sub-surfaces.Results indicated that high graphite content contributed to the formation of a protective MML.When the MML formed on the tribo-surface as graphite content increases, both the friction coefficient and wear rate greatly decreased. The friction coefficient with a stable value of 0.075 and wear rate of 6.10×10 -16 (m 3 /N• m) were the lowest when an apparent tribo-layer appeared at the graphite content of 38 vol. %. The characteristics of the MML and its influences on wear mechanisms of the composites are discussed. The MML existing on the worn surface protected the materials from severe adhesion and abrasion, the predominant wear mechanisms changed to delamination, which resulted in the drastic changes in wear resistance and friction coefficient.
