Nitrided Sample

Abstract The compound zone is more commonly known as the white layer, simply because when the nitrided sample is sectioned through the case, and then polished and etched with a standard solution of nital (2 to 5% nitric acid and alcohol), the immediate surface etches out white in appearance above the nitrided case. This chapter focuses on the methods to control the compound zone or white layer. It first provides information on a test to determine the presence of the white layer, and discusses the processes involved in the reduction of the compound zone by the two-stage process. Next, it describes the methods for controlling compound zone formation, and, finally, reviews the factors related to the determination of case depth nitriding.

Nitrided Case

Abstract Examining and evaluating the nitrided case is generally accomplished by hardness testing and microscopic examination. This chapter discusses both characterization methods, as well as sample preparation. The discussion covers the process, advantages, and disadvantages of these methods. The chapter also discusses the processes involved in the etching of the sample after microhardness testing and provides some practices that contribute to the safe preparation of specimens. Examples of nitrided case microstructures are also presented.
