Description
WB2(紺色のデータポイント)では、Efはω型のショットキー欠陥濃度の増加に伴ってのみ増加する。しかし、Efは最初はα型のショットキー欠陥濃度の増加に伴って(約10at:%まで)減少する。WB2の2つのEf-対-欠陥濃度曲線(α型またはω型を有する)は、約8at:%の空孔濃度で交差し、そこからα型が勝る、図8cを参照。
傾向は、化学組成だけでは説明できず、フィルムの形態や残留応力と関連する。X線回折では、全ての温度と組成において構造に大きな変化は見られなかった。二元α-VB2コーティングは800℃でのアニール後に剥離したのに対し、タングステンを含むコーティングは全て基板上に残っていたため、アニールされたα-VB2のデータは得られなかった。金属副格子上のWが5at:%および13at:%のコーティングは、Ta=800℃でのアニール後に2GPaの硬度低下を示したが、最も高いW合金コーティング(V0.69W0.21B2)では、約2GPaのHの増加(42.5±0.9GPaまで)を示した。調査したすべての三元コーティングは、1000℃および1200℃の間でアニールした後に最高硬度を示した。例えば、最も高いW含有コーティング(V0.69W0.21B2)は、1時間アニールすると、39GPaから43GPaまで堆積時の硬度が増加し、1200℃または1400℃でアニールすると40GPa(堆積時の値に近い)までわずかに減少することを示した(図11a)。
これは、H/EとH3/E2の値も、一般的な結果ではないアニール温度(少なくともTa≦1200℃でアニールした場合)の上昇に伴って増加するという結果につながる。X線回折の研究(個々のアニール温度の後)は、追加の相を示さず、また、個々のXRDピーク(単相α-V1-xWxB2の代表)は、その形状のほとんど変化を示さない(示されていない)。これは、図12aおよびbに示すように、それぞれ1000℃および1400℃で1時間真空アニールした後の最も高いW含有コーティング(V0.69W0.21B2)についての断面TEM研究と一致する。
