Life assessment prognostic modelling for multi-layered coating systems using a multidisciplinary approach

Life assessment prognostic modelling for multi-layered coating systems using a multidisciplinary approach

The multidisciplinary approach has been adopted to model the formation and propagation of blistering effect for evaluation of useful coating life in the multi-layered coating–substrate system. A prognostic model of de-bonding driving force has been formulated as a function of material science, solid mechanics and fracture mechanics properties to estimate critical, safe and fail conditions of the coating–substrate system. The blister growth velocity rate is also included in the developed model to estimate the blister propagation as a function of diffusion-induced stress and residual stress. The proposed prognostic modelling for the formation and propagation of blistering effect are combined to form an assessment model for the evaluation of useful coating life of the multi-layered coating–substrate system and validated through experimental observation.

Abstract

The multidisciplinary approach has been adopted to model the formation and propagation of blistering effect for evaluation of useful coating life in the multi-layered coating–substrate system. A prognostic model of de-bonding driving force has been formulated as a function of material science, solid mechanics and fracture mechanics properties to estimate critical, safe and fail conditions of the coating–substrate system. The blister growth velocity rate is also included in the developed model to estimate the blister propagation as a function of diffusion-induced stress and residual stress. The proposed prognostic modelling for the formation and propagation of blistering effect are combined to form an assessment model for the evaluation of useful coating life of the multi-layered coating–substrate system and validated through experimental observation.
