THERMAL SPRAY MAINTENANCE DEVICE

摘要

PURPOSE:To provide a thermal spray maintenance device capable of mixing homogeneously the fine particles including metal powder and oxygen gas to afford an excellent ignitability and adhesive strength. CONSTITUTION:The fine particles containing metal powder and oxygen gas are fed into a mixing chamber 11 through separate lines. The mixing chamber 11 has an open inlet end for the oxygen gas and a stirring chamber 15 for mixed fluid at the other end. A thermal spray nozzle 14 is provided between the stirring chamber 15 and the mixing chamber 11 extending from the chamber wall in a T-shaped arrangement. The fine particles and the oxygen gas fed into the mixing chamber 11 are homogeneously mixed in the mixing and stirring chamber and discharged from the thermal spray nozzle 14.
