One Approach to Eddy Current Testing of Carburized Parts

Abstract

Through DOE (design of experiment), ЕТ (eddy current testing) is included and proven as a quality indicator of carburizing, quenching and tempering of hydraulic motor parts. A method is suggested for calibrating NDT (non-destructive testing) by means of combined representation of regression models in the field of the technological factors of heat treatment and contour control charts. A method is presented here for choosing the working frequency for ET. It is also suggested that experimental design be considered a basic building element in the methodology of carburized parts ET. This article also presents a methodology for conducting eddy current testing in industrial settings.
