Abstract

A heat treated gear wheel manufactured from 17CrNiMo6 steel was analyzed. Metallurgical examination revealed decarburization on the gear tooth up to about 0.5 mm depth. The hardness survey carried out also indicated the same result. The retained austenite in the tooth close to the flank was determined to be less than 5 vol%. The residual compressive stresses on the tooth flank were measured to be in the range 250 to 440 MPa. The microstructure of the gear was found to be satisfactory except for the surface decarburization.
