Summary: (ID# 8321) This presentation explains the importance of process atmosphere, how it influences the surface characteristics of parts, and the concept of ‘atmosphere potential’ as a controlling parameter for carburizing and nitriding processes. Various types of sensors and methods for measuring the atmosphere potential are presented. The principle of operation, advantages and disadvantages of each are also discussed.
