Abstract
【解決手段】上記課題を解決するために、圧縮部、スロート部、及びそのスロート部から先広がりで円錐状の膨脹部とを備え、原料粉末をその融点以下の作動ガスを用いて該圧縮部のノズル入口から流入させ、該膨脹部先端のノズル出口より超音速流として噴出させるコールドスプレー用のノズルとして、圧縮部がノズル入口側の予熱領域と圧縮領域とを備えることを特徴とするノズルを採用する。
【選択図】図1
Description
実施例で用いたコールドスプレー用の試験ノズルは、従来形状のノズルに使用する圧縮部を、円錐形状はそのままで、出口の内径が20mmφになるように、先端部を切断し、チャンバーとして用いた。この切断部分に内径20mmφの円筒状の予熱領域を接続した。そして圧縮領域は、予熱領域からスロート部に向かう、長さが150mmの円錐形状とした。そして、圧縮部の長さを調整するために、圧縮領域の長さを一定として、予熱領域の長さが異なる5種類を製作した。このようにして、圧縮部全体の長さが50mm、100mm、200mm、500mmそして800mmの、5種類のコールドスプレー用のノズルを製作した。また、スロート部から先広がりで円錐状の膨脹部には、スロート径が2mmφ、噴出部の径が6mmφの逆円錐形であり、長さが200mmの従来ノズルを用いた。しかし、上記ノズルの全体構成は、従来の圧縮部を切断したチャンバーを用いたため、パウダーポートが予熱領域内に位置していた。そこで、有効な加熱長さを明確にするため、各実施例の圧縮部長さは、パウダーポートの位置からスロート部までの長さと定義した。
基材に対する皮膜の形成は、図2に示す構成のコールドスプレー装置に、上記に製作した5種類の予熱領域を用い、実施例1〜実施例5としてCS溶射試験を行なった。
