Abstract Scope |
The tribological properties of SS 304 and Ti6Al4V substrates were assessed by using an automated bio-tribometer with four reciprocating geometries (linear, circle, square, and eight) under dry and simulated body fluid (SBF) lubrication against zirconia pin. The variation of both CoF and wear rate was observed to be Linear < Circle < Square < Eight in dry as well as lubricated condition, indicating the complexity of eight geometry. The CoF and wear rate values of Ti6Al4V alloy, in dry condition, were reported in the range of 0.75-0.90 and 0.34-0.94 mm^3/Nm, respectively. The formation of lubricant film under SBF lubrication helped in decreasing CoF and wear rate nearly by 20% than that of in dry condition. However, the Finite Element Analysis study reported the shear forces exhibited by each geometry, confirmed the concomitant actions of rapid change in the direction of motion in a complex geometry that contributed to increased wear. |
