THERMAL SPRAY POWDER AND METHOD FOR MANUFACTURING THERMAL SPRAY COATING
To provide a technique capable of maintaining fluidity suitable for thermal spray and supplying finer ceramic particles during thermal spray.SOLUTION: Thermal spray powder is constituted of ceramic particles. When comparing the thermal spray powder after performing atmospheric pressure plasma thermal spray in water with that before the thermal-spray on the following conditions: plasma working gas: argon (Ar) gas of 50 psi and helium (helium) gas of 50 psi, a plasma output: 36 kW, the supply rate of the thermal spray powder: 20 g/min and a thermal spray distance: 400 mm, the value of the average particle diameter (D50) of the thermal spray powder on the basis of a laser diffraction and scattering method is smaller by at least 25%.SELECTED DRAWING: Figure 5
【課題】溶射に適切な流動性が維持され、かつ、溶射に際して、より微細化されたセラミック粒子を供給できる技術を提供する。【解決手段】ここで開示される溶射用粉末は、セラミック粒子により構成されている。この溶射用粉末は、該溶射用粉末を下記条件：プラズマ作動ガス：アルゴン（Ａｒ）ガス：５０ｐｓｉ；および、ヘリウム（Ｈｅ）ガス：５０ｐｓｉプラズマ出力：３６ｋＷ溶射用粉末の供給速度：２０ｇ／ｍｉｎ溶射距離：４００ｍｍで水中に大気圧プラズマ溶射した後と該溶射前とを比較したときに、該溶射用粉末のレーザ回折散乱法に基づく平均粒子径（Ｄ５０）の値が少なくとも２５％小さくなることを特徴とする。【選択図】図５
