“…Later as graphene is further increased to (5%) i.e., Al-0.5C-5G we can see the reduction compared to 3% Gr in the matrix because of agglomeration due to the addition of more buttressing milieu. This is due to the capacity stentorian ability of the bolstering in the milieu material [16][17][18][19] . From Figure 7 solidity surges with the upsurge in keeping Carbon Nanotube (CNT) continual and Graphene (Gr) gratified in the factual.…”

Composites containing metal at least in two constituent parts are metal matrix composites. Another material may also be used like organic compounds or ceramics, in addition to a different metal. In the current work Al5056 aluminium powder is used as the matrix material having an average particle size was about 35±5 μm and Carbon Nanotube (CNT) and Graphene (Gr) are used as reinforcement materials. Hybrid composites are developed using an advanced powder metallurgy technique process. Also, in the existing work microstructure characterization was performed using advanced techniques. Hardness, Tensile and wear tests are conducted as per ASTM standards. Mechanical properties improved with the increase in amalgams in the matrix. The wear surface morphology of Al alloy shows a rough surface with more grooves and ridges compared to the wear surface morphology of Al5056/CNT-Gr hybrid composites. Wear debris results of Al alloy show more debris chips out of the material compared to Al5056/CNT-Gr hybrid composites.

“…Also, the time required to fill the porous, solid perform and efficiency of the processes are other critical factors that decide the final properties of the composite in this case. However, improved dispersion has been reported for Al-MWCNT [38][39][40][41][42][43] and Mg-MWCNT composites. As compared to powder metallurgy, the melting techniques should ideally produce much denser composites.…”

Utilizing Laser Engineered Net Shaping (LENS), nanocomposites were generated by mechanically combining metal powders with various amounts of multi-walled carbon nanotubes (CNTs). To produce free-standing bulk structures and coatings, the LM6 (Al-12Si-0.6Fe-0.5Mn-0.3Mg-0.1Ni-0.1Zn) alloy was chosen owing to its exceptional corrosion resistance in typical atmospheric and marine environments. The LENS technique was employed to fabricate the coating-substrate interface for LM6 coated Al-2024 and MWCNT-LM6 coated Al-2024. The addition of MWCNTs to the Al-Si matrix enhanced the tribological properties of LM6. SEM images revealed abrasive wear as the primary wear mechanism. A pin-ondisc wear tester was utilized to study the friction and wear behavior of the composite under a load of 1 N and a sliding speed of 50 mms-1. The addition of MWCNTs resulted in a reduction of the friction coefficient because of the MWCNT's selflubricating characteristic and unique topological structure. Moreover, the volumetric wear rate dropped considerably, and thermal properties were significantly enhanced with the inclusion of MWCNTs. A 25% increase in thermal conductivity was seen after the addition of 8% vol MWCNTs to LM6 coated Al-2024.

The 17-4 PH stainless steel possesses distinguished applications due to its inherent properties. Higher surface roughness in Selective Laser Melting (SLM) parts limits their use in a wide range of applications. Higher surface roughness deteriorates the important functional properties (strength, fatigue, corrosion resistance and so on). Therefore, an attempt is being made to reduce the surface roughness during the processing stage itself, rather than the dependency of costly secondary post-processing routes. Taguchi L9 experiments are conducted to analyze the laser power, scan speed and hatch distance influence on the surface roughness of SLM parts. Laser power showed the highest percentage contribution equal to 83.37%, followed by scan speed of 9.92% and hatch distance of 6.71%, respectively. Taguchi method determined optimal conditions (laser power: 270 W, scan speed: 1000 mm/s and hatch distance: 0.08 mm) through Pareto analysis of variance resulted in low values of surface roughness with a value equal to 4.11 µm. The results of the optimal condition can be used by any novice user to obtain better surface quality in SLM parts. Further, the Taguchi method can be applied to optimize any process with limited experimental trials and resources.
