In the production of Ink stone and Goishi, a large amount of powder appears as a byproduct. In a previous report, when the thermal spray frame is covered with N2 gas and CO2 gas as auxiliary gas, the Nachiguro coating can be made black. However, Nachiguro coating didn’t become completely black. We examined whether the Nachiguro coating was oxidized by hitting the thermal spray flame or oxidized in the thermal spray flame. In this paper, we report the results of examining the cause of oxidation by collecting Nachiguro stone powder in the thermal spray flame., application/pdf}, pages = {27--28}, title = {那智黒石粉末利用法のFS検討 -溶射フレーム中の粉末状態について-}, year = {2020}, yomi = {ナカムラ, ノブヒロ and クガイ, カツヤ} }
