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).
