Abstract
【解決手段】スプレーノズル(10)は、ノズル本体(1、2、3)と、ノズル本体(1、2、3)の先端に連結するノズル先端部4と、ノズル先端部4におけるキャリアガスの通過路内に配され、皮膜材料の軌道を変更する少なくとも1つの軌道変更部6と、を備える。

Description
最初に、図2を参照して、本実施の形態に係るスプレーノズル10を用いるコールドスプレー装置(皮膜形成装置)100について説明する。
近年、コールドスプレー法と呼ばれる皮膜形成法が利用されている。コールドスプレー法は、皮膜材料の融点または軟化温度よりも低い温度のキャリアガスを高速流にし、そのキャリアガス流中に皮膜材料を投入し加速させ、固相状態のまま基材等に高速で衝突させて皮膜を形成する方法である。

(コールドスプレー装置100)
図2は、コールドスプレー装置100の概略図である。図2に示すように、コールドスプレー装置100は、タンク110と、ヒーター120と、スプレーノズル10と、フィーダ140と、基材ホルダー150と、制御装置(不図示)とを備える。
次に、スプレーノズル10を図1等により説明する。図1は、スプレーノズル10の断面図である。
図3は、第3胴体部3にノズル先端部4が取り付けられた様子を示す写真である。図4は、第3胴体部3からノズル先端部4が取り外された様子を示す図である。図5は、ノズル先端部4の斜視図である。
図6は、軌道変更部6により生ずる皮膜材料Mの軌道の変化を説明する概略図である。図6において、図面上側から下側に向かって皮膜材料Mが供給される。皮膜材料Mの軌道上には軌道変更部6が設けられている。軌道変更部6に皮膜材料Mが衝突すると、皮膜材料Mは、その軌道を変化させ、変化した後の軌道に沿って基材20の表面に到達する。その結果、ノズル先端部4が軌道変更部6を備えない場合と比較すると、基材20上の皮膜領域が変化する。このようにして、ノズル先端部4は、軌道変更部6の数量、サイズ、形状、又は位置等を適宜変化させることにより基材20の表面における皮膜領域を制御することができる。
図7は、軌道変更部6を使用せずに皮膜材料を成膜した基材20の表面の写真であり、(a)はノズル先端部4を示し、(b)は基材20の表面の写真を示す。図8は、軌道変更部6を1つ使用して皮膜材料を成膜した基材20の表面の写真であり、(a)はノズル先端部4を示し、(b)は基材20の表面の写真を示す。図9は、軌道変更部6を2つ使用して皮膜材料を成膜した基材20の表面の写真であり、(a)はノズル先端部4を示し、(b)は基材20の表面の写真を示す。図7(b)、図8(b)、及び図9(b)それぞれにおいて、図面上下方向がノズルの動作する方向であり、破線の内側が皮膜領域を示す。
図8等を用いて説明したように、軌道変更部6は様々な位置に取り付けられる。
