This work is based on the study of wear behaviour of a DIN 16MnCr5 steel pair of helical gears. Vickers micro hardness tests were carried out and an in-depth study of two zones of the material in question was studied: hardness analysis of the material composing the gear body and analysis of the hardness of the teeth in the area of head of the tooth and study of the hardness along the profile of the tooth. Finally, wear tests were carried out on the material and its behavior on dry and lubricated wear was evaluated using a pin-on-disc test machine. Parameters as friction forces, friction coefficients, volume loss of material and temperatures in function of applied forces are determinate for different tests.
