“…Tough plenty of reinforcements were available, titanium dioxide is the one that can resist wear and corrosion [6] and molybdenum disulphide is the lubricant that helps to reduce the frictional efects [7]. Studies on the TiO 2 and graphite-reinforced copper composites were done and found that the addition of reinforcement improved the workability behavior and the strength coefcient [2,8]. Investigations into the electrical and mechanical properties of copper composites with nanotitanium dioxide were done, and the outcome of the addition of 1.72 volume percentage showed higher yield strength with electrical conductivity [9].…”

The paper deals with the properties of copper-based composites. Copper is contributing to the field of automobiles and aerospace industries. The tribological properties of copper are not found to be satisfactory, which may be attributed to the support of producing copper matrix composites with extensive investigations into their properties. Coper-based hybrid composites were fabricated by reinforcing titanium dioxide (TiO2) and molybdenum disulphide (MoS2) to enhance the wear and mechanical properties of copper composites. Three specimens were prepared by powder metallurgy process with the designations of Cu + 5wt.%TiO2, Cu + 5wt.%TiO2 + 2wt.% MoS2, and Cu + 5wt.% TiO2 + 4wt.% MoS2. The metallurgical analysis was done on the specimens using X-ray diffraction (XRD) analysis which confirms the presence and distribution of Cu, TiO2, and MoS2 particles in the specimens. The wear rate was studied on the specimens concerning the sliding velocity, load, and MoS2 content. The statistical analysis and Taguchi analysis highlight the influencing parameters on the wear rate of the material. Linear regression equations were developed to predict the wear rate using DoE. Through this analysis, the sliding velocity of 3 m/s, a load of 30 N, and a 4% addition of MoS2 were identified as the optimum parameters for the minimal wear rate. The wear mechanism was analyzed using scanning electron microscopy techniques to reveal the adhesion, delamination, and oxidation.

“…Çelikyürek and Biçer (2016) have prepared bronze matrix composites reinforced with Ni3 Al particles by means of powder metallurgy technique and reported that the strength of powder metallurgy bronze was higher than the conventional composites. Ilayaraja et al (2017) have produced hybrid copper matrix composites using powder metallurgy method with reinforcement as 5 wt. % of titanium dioxide and various weight percentage of graphite.…”

Bronze with addition of graphite, produced by powder metallurgy processes are widely used in textile and food industries as bearings and bushes. Addition of graphite serves to reduce sliding contact between machine parts, especially where grease and oil lubricant cannot be used. Sintered bronze-graphite composite with various volume percentage of graphite at different particle size and at varying compaction load was prepared. The surface morphology of the composites was experimented by scanning electron microscope. The sintered composites exhibited reduced porosity and improved relative density. The theoretical, green, sintered and relative density of the specimens were determined. It was found that the porosity of the composites decreased with increase in volume percentage of graphite. The effect of variation in particle size of graphite, volume of graphite content and compaction load on hardness of the sintered composites were studied. The scratch test for all the specimens at a constant load of 10 N was conducted

“…20 Ilayaraja et al manufactured a copper-matrix composite with TiO 2 and graphite as the reinforcement using the powder-metallurgy technique to investigate the formability behaviour and found the addition of the reinforcement improved the true stresses. 21 Elango et al manufactured a hybrid aluminium-matrix composite with TiO 2 and silicon carbide to investigate its tribological behaviour and observed an increased hardness with increased reinforcement additions. 22 With reference to the earlier studies, an attempt was made to synthesize an aluminium metal-matrix composite AA7075 with TiC as the reinforcement for different weight percentages, i.e., 0 %, 8 % and 16 %, using the powder-metallurgy technique and to study the formability behaviour of that composite.…”

Aluminium 7075 is frequently used in aircraft structures. Aluminium metal-matrix composites with 0 % TiC (w/%), 8 % TiC and 16 % TiC were produced using the powder-metallurgy technique. Metallurgical studies, such as X-ray diffraction (XRD) and scanning electron microscopy (SEM), were made to confirm the occurrence of reinforcements. A cold-upset test was conducted on the synthesized composites and different stress parameters were calculated to study the forming behaviour of the produced composite in the tri-axial stress-state condition. The values of the stresses were found to be highest for the aluminium composite reinforced with AA7075 + 16 % TiC.
