Experimental analysis of shot peening on carburized or carbonitrided parts

摘要

This experimental study focuses on the influence of shot peening on parts initially treated by carburizing or carbonitriding. Experimental investigations have been carried out: optical observations of the microstructures, in-depth hardness measurement, X-ray diffraction analysis of residual stresses. A comparison is made between the carburizing anad the carbonitriding treatments.
