Microstructure and Mechanical Performance of Tin-Based Babbitt Alloy Containing Iron Oxide and Silica Nanoparticles

Iron oxide and silica nanoparticles were individually incorporated in tin-based Babbitt alloy combined to prepare a novel class of nanocomposites for bearing material applications. The route liquid metallurgy combination with the stirring technique was adopted manufacture nanocomposites. Microstructural evolution mechanical property evaluation performed by optical electron microscopy, EDS, hardness, compression, wear tests. morphology Cu6Sn5 phase changed from elongated spherical microstructures solitary addition 0.5 wt% iron improved hardness compressive strength but adversely affected properties increasing weight loss friction coefficient value. In contrast, could not significantly increase it improve tribological reducing Tin-based showed 89.22 ± 0.50 MPa after showing rise ~11%. effect both types considerable results, i.e., ~7.9% (86.75 0.68 MPa). balanced approach incorporating dual reinforcements 0.25 intermediately strength, decreased loss.
