Deterministic analytical modeling of coupled electrical conductivity and tribological behavior in Cu Zn Ni Si alloys

In this study, the combined influence of material composition, load, and sliding velocity on the properties of wear and electrical properties of copper–zinc–nickel–silicon alloys is investigated. An approach based on deterministic modeling is recommended to predict the influence of zinc content and nickel-silicon reinforced material under various loads. Wear behavior and electrical transport characteristics are correlated through the material composition and resistivity relationship. From these results, it can be observed that there is a clear trend of increasing electrical conductivity with an increase in the amount of the alloy to up to 121 percent of the IACS value. Wear is maintained at the level of 10⁻ 5 mm 3 / (Nm), meaning there is consistency of performance at loads between 5 and 20 newtons. Higher loads lead to higher wear as well as higher temperatures, while higher sliding velocities reduce friction and surface interaction. It is believed by the suggested deterministic model that the composition of the alloy plays an important role in determining the electric conductivity as well as wear, whereas the load applied and the sliding speed determine the frictional and thermal response. The proposed approach can be used to evaluate the behavior of the alloy through a repeatable methodology. However, it is limited to simulation-based verification within a specific range of parameters.
