ABSTRACT:
A feedback control system for performing and controlling the laser alloying of a workpiece. The apparatus includes a laser beam delivery system, a movement system capable of causing relative movement between a laser beam and a workpiece being irradiated by the laser beam, a precursor application system capable of applying a precursor at a desired rate to the surface of a moving workpiece, and a control system capable of receiving input signals indicative of one or more measured process parameters, processing those signals, and transmitting a control signal capable of controlling the laser beam delivery system, movement system, and/or precursor application system. Other embodiments of the invention utilize a variety of process parameter measuring devices in conjunction with the control system. These devices include, but are not limited to, temperature transducers, infrared detectors, and emission spectra measuring devices.
