Abstract: A system (100), apparatus (110), and method (900) for monitored thermal spraying. One or more sensors (610) are used to capture one or more types of measurements (650) to monitor the thermal spraying process. A processor (710) can analyze a waveform (750) of measurements (650), such as electrical measurements (652). The processor (710) can then initiate a response (770) such as a warning (772) or an automatic adjustment (790) that is triggered by an identified operating condition (800).

Abstract: A coating system that applies a coating of particles to a surface of an article. The coating system comprises a hybrid plasma torch which may include a cathode, a first plasma gas chamber, a first mixing chamber, a plasma generator for generating an arc column of plasma, a second mixing chamber for mixing a main gas, an at least partially ionized first plasma gas and a second gas that was mixed in the first mixing chamber, wherein the second mixing chamber is dimensioned to receive a plurality of powder particles suspended in a carrier gas, and an accelerator assembly for accelerating the mixture of the main gas, the at least partially ionized first plasma gas, the second plasma gas and the powder particles into a high-velocity stream and for directing the high-velocity stream against the surface of the article. A method of applying the coating of particles is also provided.

Abstract: A system (100), apparatus (110), and method (900) for creating a particle stream (70) that is deflected with a secondary gas (518) such as air before coming into contact with the treated substrate surface (80). The system (100) can be implemented as an improvement to a prior art PTWA (plasma transferred wire arc) thermal spraying apparatus (50) by using a non-symmetrical passageway configuration (549). Such a configuration can be an attribute of a nozzle (220) or a secondary gas director (576) such as an air baffle (578).
