Surface Integrity Evaluation Based on Barkhausen Noise Analysis: A Conceptual Approach.

Destructive testing methods, such as Vickers hardness test or hole drilling methods for residual stress evaluation have long been conventional approaches in manufacturing to investigate surface integrity and are widely being used in industry to date. However, their limitations in terms of material damage and high costs have spurred the exploration of non-destructive testing alternatives like Barkhausen noise analysis. So far almost exclusively data-driven and empirical models have been used to employ Barkhausen noise analysis as a non-destructive testing method in manufacturing. These models provide valid predictions for the manufacturing process and the specific material studied. However, they lack the capability to be generalized to other process conditions and materials. Physics-based models on the other hand provide the generalizability needed for widespread industrial applications. This strength turns out to be a weakness when trying to extract residual stress or microstructural properties from these models. The goal of this paper is, to provide an overview of published data-driven models in literature with thematic relevance to manufacturing processes and to propose a new, generalizable model.
