METHOD FOR INCREASING THE STRENGTH OF A PART

摘要

Disclosed is a method for increasing the strength of a part, especially a crankshaft, which is subject to torsional and bending stress. In said method, essentially the entire part is provided with a nitride layer in a first step, the nitride layer is at least partially removed in at least one highly stressed area of the part by means of a machining process in a second step, and the at least one highly stressed area of the part from which the nitride layer has been removed is mechanically work-hardened in a third step.
