Numerical Analysis of Wear Characteristics of Zirconia Coated Aluminum 6061 Alloy

Abstract

Any mechanical systems with moving parts encounter the problem of wear and industriesacross the world are trying to reduce its detrimental effects. In this paper, Finite Element Method (FEM) is used for analysis of wear characteristics of Yttrium stabilized Zirconia coating on Al6061 Aluminum alloy. Aluminum alloy 6061, having high strength to weight ratio, is used as the substrate material upon which Thermal Barrier Coating (TBC) is applied. Friction and wear coefficient obtained from Continuous Sliding Motion (CSM) of Yttrium stabilized Zirconia coating over Aluminum oxide disc material is used for the numerical analysis inputs. Tribological characteristics such as contact pressure, frictional stress and wear thickness are evaluated numerically using ANSYS Mechanical based on Archard wear model.
