SURFACE TREATMENT APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a surface treatment apparatus which can improve a transfer rate of a projection material and can decrease surface roughness, when surface-treating an article to be treated by jetting the projection material thereto while induction-heating the article to be treated. SOLUTION: This surface treatment apparatus includes: a chamber 110; a gas-supplying part 142 for introducing nitrogen gas into the chamber 110; a support 120 which is arranged in the chamber 110 and supports the article to be treated W; an induction heating coil 130 which is arranged around the support 12 and heats the article to be treated W; a high-frequency-wave-applying unit 200 which supplies a high-frequency electric current to the induction heating coil 130 and makes the induction heating coil 130 induction-heat the article to be treated W; and a jet nozzle 140 for jetting the projection material together with the nitrogen gas toward the support 120.
