Description
つまり、不活性ガスの供給量を制御することで、燃料の供給量をも制御され、不活性ガスを増大すれば燃料が減少し、逆に不活性ガスの供給量を減少すれば燃料が増大することとなり、不活性ガスによる燃焼ガスの希釈のみならず、燃料の増減によっても温度制御を行うことができた。
(2) 導管
(3) 粒子混合部
(4) ノズル
(5) 不活性ガス混合室
Claims (1)
- 導管(2)の一端部に、燃料ガスを燃焼してノズル(4)より他端に向かってジェット流を噴射する燃焼室(1)を設け、前記導管(2)内のジェット流に噴射用の粒子を混合する粒子混合部(3)が設けてあるHVOF溶射装置であって、
前記燃焼室(1)のノズル(4)側に、冷却用ガスを混合する混合室(5)が設けてあり、
前記混合室(5)に前記冷却用ガスの導入管が接続されており、
前記冷却用ガスの導入管の軸方向が前記導管(2)の軸方向に垂直とされており、
前記燃焼室に前記混合室が直結されており、
前記燃焼室の径に対して前記混合室の径が小さくされていることを特徴とするHVOF溶射装置。
