“…Particularly, the addition of n‐TiB 2 particles on aluminum alloys would prevent the formation of brittle products in the matrix/reinforcement interface. In addition, it would allow improving mechanical properties of the alloy, inducing weight reduction . Moreover, the excellent processability and weldability of the A6005 aluminum alloy together with its low cost make possible its implementation at the industrial scale.…”

Corrosion susceptibility of the A6005 alloy reinforced with n‐TiB2 was studied through electrochemical tests. The mechanical alloying (MA) technique was used as the processing route and a posterior hot extrusion was employed to consolidate the powders. Bulk samples were characterized by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy, and microhardness tests. The combination of both MA processing and 5 wt% n‐TiB2 addition in the aluminum matrix produced 61% increase of microhardness. Electrochemical tests were performed in 3.5 wt% NaCl solution to assess the effect of MA processing and TiB2 presence on corrosion behavior. The corrosion resistance of the samples processed by MA increased slightly compared with the base A6005 alloy. The amorphous Al2O3 phase formed during MA processing was the cause of this increase, providing continuity to the passive layer. Furthermore, the addition of TiB2 on the sample processed by MA did not significantly affect corrosion resistance. Polarization tests confirmed that the reinforced sample had similar icorr to that of the unreinforced alloy, and cyclic polarization tests revealed that pit nucleation sites were localized in the interface between Al2O3 and the aluminum matrix.

“…Roy et al [9] concluded that the mechanical and wear properties are improved with the presence of SiC and CB in aluminium 7075 matrix. James et al [3] concluded that the presence of SiC and Al 2 O 3 will improve the rate of wear in Aluminium alloy. Palanivel et al [8] reported that hardness was incresed with the presence of BN nanoparticles in AA6082.…”

A composite material contains different reinforcing elements added to the major material that forms the base matrix. In this work Aluminium 7075 matrix was reinforced with 12% TiB2and 4%, 6% and 8% Cr2O3 and the wear behavior of this composite was studied. The composite material was prepared by the process of stir casting. The rate of specific wear was measured for different reinforcements under varying velocity and load. The Scanning Electron Microscope images of the worn-out surfaces were used to investigate the wear pattern. The wear rate could further be extrapolated using fuzzy logic and were compared with the experimental results.

“…It was observed that the hardness and the UTS of the composites were enhanced with the increase in the content of SiC. In addition to the above works, researchers had also developed certain hybrid metal matrix composites, such as Al6061/SiC/Graphite [11], Al2219/B 4 C/MoS 2 [12], Al6061/SiC/TiB 2 [13], Al6061/SiC/ B 4 C [14], and studied the mechanical and tribological properties of the composites. Further, few researchers used the concept of RSM to model the dry wear phenomenon of MMCs.…”

An attempt is made to find the mechanical and tribological properties of Al6061/Gr metal matrix composites (MMC) produced using stir casting method. It is important to note that the certain components require high hardness and wear resistance to fulfil the functional requirements, the said properties of the MMCs influenced largely on the condition with which they are produced or treated. Therefore, in the present paper the composites are tested in two stages that is before T6 heat treatment and after T6 heat treatment respectively. The composites are made with Al6061 alloy as matrix and graphite with 3%, 6%, 9% and 12% by wt is considered as reinforcement. Once the composites are prepared, they are examined for their microstructural, mechanical, and tribological properties. Further, a response surface methodology (RSM) has been used to model the wear loss and coefficient of friction for both before and after T6 heat treatment of MMCs. The non-linear regression model obtained is validated both statistically and with the help of experimental test cases. The evidence of wear phenomenon has been observed with the help of Scanning Electron Microscopy (SEM). Further, fuzzy grey relational Technique has been used to determine the multi performance index for the dry sliding wear and friction phenomenon of the developed composite.
