Evaluating Wear Performance of Silicon Nitride-Hexagonal Boron Nitride Composite Using Taguchi Method


The goal of bio-tribology research is to determine which biomaterials will wear the least. Recently, silicon nitride (Si3N4) has been suggested as a substitute material for hip and knee joint replacement. Hexagonal boron nitride can be used to improve Si3N4’s wear characteristics (hBN).

Methods/Analysis: In order to reduce wear loss, this study evaluates the sliding wear behaviour of Si3N4-hBN composite against alumina and steel (ASTM 316L). The impact of hBN addition on Si3N4 wear performance was investigated. The trials were designed using the Design of Experiments (DoE) – orthogonal array Taguchi approach to assess the impact of the addition of hBN on the silicon nitride material’s wear properties.

Findings: Taguchi analysis recommends 15N load and 8 percent volume of hBN against alumina and 15N load and 12 percent volume of hBN against steel to reduce Si3N4 wear loss. The relationship between load and hBN addition has a significant impact on silicon nitride’s wear resistance.
