- 軸方向に貫通する材料搬送管を有する主陽極と、前記主陽極を囲むとともに前記主陽極の軸方向前方に位置する主開口部を有する主外套と、前記主外套を冷却する冷却要素とを有する主トーチと、前記主陽極の中心軸と交差する中心軸を有する副陰極と、前記副陰極を囲むとともに前記副陰極の軸方向前方に位置する副開口部とを有する副外套とを有する複数の副トーチとを備え、前記主開口部および前記副開口部を通じて前記主陽極および前記副陰極の間に形成されるプラズマによって前記材料搬送管から放出または拡散される流動性のある材料を加熱することにより溶融粒子を生成し、前記溶融粒子を前記主陽極の軸方向前方に配置されている基材に吹き付けることにより前記材料によって構成される皮膜を前記基材の上に形成するプラズマ溶射装置において、
前記主陽極の先端部に、前記主陽極の径方向について前記材料搬送管よりも外側から連続的に縮径しながら前記主陽極の軸方向後方に向かってくぼんでいる第1凹部と、前記主陽極の径方向について前記第1凹部の内縁から前記材料搬送管に至るまで連続的または断続的に縮径しながら前記主陽極の軸方向後方に向かって前記第1凹部よりも大きくまたは急峻にくぼんでいる第2凹部とが形成され、
前記材料が、前記材料搬送管から放出又は拡散され、かつ、前記第2凹部により画定される空間及び前記第1凹部により画定される空間を通過した後に、初めて前記主陽極及び前記副陰極の間に形成される前記プラズマと接触するように、前記主トーチ及び前記副トーチが配置されていることを特徴とするプラズマ溶射装置。 - 請求項1記載のプラズマ溶射装置において、
前記材料搬送管は、前記材料を搬送する内管と、前記内管の外側に配置され、かつ、前記材料の飛散を補助するガスを供給する外管とを備えることを特徴とするプラズマ溶射装置。
