Plasma gun nozzle corrosion prevention and gun nozzle corrosion prevention method

摘要

Nozzle for thermal spray gun, thermal spray gun, and method for forming nozzle. The nozzle has a central cavity and an outer surface and includes a nozzle body configured to be inserted into a spray gun and a water-coolable surface coating applied to at least a portion of the outer surface. The water-coolable surface coating is configured to protect the outer surface from chemical interaction with cooling water guided through the spray gun.
