Abstract:
1. A prepping and coating system comprising: a nozzle comprising an ultrasonic transducer having a microtip that modulates a fluid stream, wherein the nozzle entrains coating particles into the fluid stream and directs the fluid stream carrying the coating particles at a surface to prep the surface, the coating particles thereby becoming smaller in size as the coating particles impinge on the surface; wherein the nozzle is pulsed waterjet nozzle; wherein said system includes a filter; wherein said system, after the fluid system is directed at the surface to prep the surface, filters non-adhered coating particles and recycles reduced-sized, non-adhered particles and wherein said nozzle subsequently entrains and directs the recycled reduced-sized particles are smaller than the particles used to prep the surface, the nozzles comprising one or more particle inlets that inject the coating particles and the reduced-sized, non-adhered particles into the nozzle, the nozzle including a mixing chamber that mixes the coating particles with the fluid stream; a control system that controls the particle delivery subsystem to control delivery of the coating particles into the nozzle.
