The process of laser beam transformation hardening is principally controlled by two independent parameters, the absorbed laser power on a given area and the interaction time. These parameters can be transformed into two functional parameters: the maximum surface temperature and the hardening depth. It has been proved that with a constant hardening depth the results hardness. residual stress. etc.) can be optimized easily with respect to only one independent parameter, the maximum surface temperature. which is applied directly in adaptive control strategies.
