Methods such as air plasma spray and electronbeam physical vapor deposition are used for thermal barrier coatings (TBC) applied to turbines,machinery parts and tools. The process-structure-property correlations to the coating technologyare very important for achieving lifetime durability and sustainability [1, 2]. An importantmeasure of coating integrity is the porosity of the surface structure [3]. Traditionally porosity ofthe deposit is obtained by microscopy of surface sections and use of software to assess theporosity based on a manual grayscale setting. As a result porosity results on surface coatings arehighly subjective.This paper evaluates six edge detection methods in MATLAB for determining porositymeasurement on a test image of a thermal barrier coating.References1.
