Abstract
【解決手段】物理蒸着が、Ti合金タービン構成部材上に修理材料を堆積させるのに使用される。裏当て足場/覆い部材52が、失われた/除去された材料の位置に隣接して小面50を越えて突出するように、エーロフォイル26に取り付けられる。ブレード26は、照準経路502の線に沿って蒸気を放出する蒸気供給源58に対して配置され得る。供給源/経路は、表面50および36に対する垂直から外れたわずかな角度θ2およびθ3内にあるのが有利である。例示的なθ2およびθ3は、30°より小さい。供給源58からの堆積は、第1の修理材料60を堆積させる。これは、エーロフォイルの失われた元の輪郭の圧力面36部分を越える表面輪郭62まで堆積させるのが有利である。
