Description
本発明の実施形態に係る成膜方法について、図面を用いて詳細に説明する。図1は、本発明の実施形態に係る成膜方法を説明する模式図である。
・ターゲット:チタン
・放電ガス:アルゴンガス
・ガス流量:50sccm
・ガス圧力:0.7Pa
・DC電力:1000W
・作動ガス:圧縮窒素
・ガス圧:1~6MPa
・ガス温度:400~450℃
・溶射距離:15mm
・トラバース速度:20~80mm/sec
・溶射用粉末溶射速度:マンガニン:10~30g/min
・作動ガス:圧縮窒素
・ガス圧:1~6MPa
・ガス温度:400~450℃
・溶射距離:15mm
・トラバース速度:20~80mm/sec
・溶射用粉末溶射速度:マンガニン:10~30g/min
セラミックス基板として酸化アルミニウム(アルミナ)を用いた。抵抗体材料としてマンガニンを用いた。また、金属被膜を形成するための金属材料としてチタン、アルミ、ニクロム、ニッケルのそれぞれを用いた。
・ターゲット:チタン
・放電ガス:アルゴンガス
・ガス流量:50sccm
・ガス圧力:0.7Pa
・DC電力:1000W
・作動ガス:圧縮窒素
・ガス圧:1~6MPa
・ガス温度:400~450℃
・溶射距離:15mm
・トラバース速度:20~80mm/sec
・溶射用粉末溶射速度:マンガニン:10~30g/min
<抵抗温度特性>
上述のようにして得られた供試体について、抵抗温度係数を測定した。
・抵抗温度係数の測定
第1金属被膜としてチタン、アルミニウムを用いた場合における、供試体の抵抗温度係数(TCR)を測定し、第1金属被膜の膜厚の変更に伴う標準値に対する抵抗温度係数の変化率を算出した。抵抗温度係数(TCR)とは、抵抗器の温度変化による内部抵抗値の変化の割合を表すものであり、下記式により表される。
ここで、Ra:基準温度における抵抗値、Ta:基準温度、R:定常状態における抵抗値、T:定常状態になる温度である。
<剥離強度試験結果>
作製された供試体について、「フォトテクニカ社製 Romulus」を用いて剥離強度測定を行った結果、アルミナ基板上にマンガニンの抵抗体被膜を成膜する際の接合層としての金属被膜の違いにより、下記の結果が得られた。
金属被膜がアルミニウムの場合 剥離強度:50MPa、
金属被膜がニクロムの場合 剥離強度:10Mpa以下
金属被膜がニッケルの場合 剥離強度:10MPa以下
抵抗温度係数の結果を図6に示した。図6に示されるように、第2金属被膜としてアルミニウムを用いた場合には、膜厚が増すと、抵抗温度特性の変化が大きくなることがわかる。また、第2金属被膜としてチタンを用いた場合には、膜厚が増しても、抵抗温度係数の変化が少なく、安定した抵抗温度特性を有することがわかる。
