A STUDY OF THE FATIGUE OF TOOL STEELS HAVING A SURFACE COATING

Abstract

CONCLUSIONS: The fatigue strength of chrome tool steel is substantially reduced as a result of applying a metallic coating by spraying, dipping, or electrolysis. The decrease occurs before and after holding the steel at an elevated temperature. Shot-peening or nitriding the surface of steel prior to application of a coating considerably increases the fatigue strength of the coated specimens. This effect also occurs after holding the coated specimens at elevated temperatures. Aluminum-silicon paint does not substantially effect the fatigue of steel. (Author)
