Investigation on the combined effect of ZnO nanorods and Y₂O₃ nanoparticles on the microstructural and mechanical response of aluminium

Effect of nano ZrB2 particles on physical, mechanical and corrosion properties of Al6061 metal-matrix nano composites through stir casting route

“…In a recent study, the mechanical properties could increase by adding ZnO nanorods and Y 2 O 3 nanoparticles into the Al matrix. The improvement in mechanical properties is due to the homogeneous distribution of reinforcement particles into Al matrix, Orowan strengthening and differences in the thermal expansion coefficient of matrix and reinforcing particles [38].…”

Mechanical and microstructure evaluation of novel hybrid TiB2/B4C aluminium metal matrix composite

“…Zhao et al [18] fabricated and investigated a hybrid Al-Cu/TiB 2 +Al 2 O 3 composite through an in situ reaction route using the stir casting technique and reported superior mechanical properties, compared with the individual composites. Bhoi N K et al [19] fabricated Al/ZnO+Y 2 O 3 hybrid composite successfully, using powder metallurgy technique and observed strong interfacial bonding between the aluminium matrix and the reinforcements. Gopinath et al [20] successfully fabricated Al6061/BN+Al 2 O 3 +C hybrid composites with different proportions using stir casting route and reported improved mechanical, wear and corrosion resistance properties than the Al6061 alloy.…”

Experimental investigation to assess the effect of graphene blended lithium grease on friction, wear, and surface morphology of 52100 chrome alloy steel contacts

“…2,5 The most commonly used lubricant nanomaterials are graphene, graphite, zinc oxide, aluminium oxide, boric acid, aluminium nitride and molybdenum disulphide. 4,[6][7][8] Among this graphene is an allotrope of carbon, consists of twodimensional layers made of covalent bond and has outstanding sliding properties compared to other carbonbased material. 1,9 The tribological advantage of graphene has been demonstrated in prior investigations particularly for rolling/sliding interactions.…”
