Abstract
【解決手段】ガスタービンのコンプレッサブレードまたはタービンブレード(1)の再形成方法であって、コンプレッサブレードまたはタービンブレード(1)の前縁(2)の少なくとも一部分が、本質的に追加材料の導入なしに、材料を硬化させて新しい形状(5)を形成するように、エネルギービーム(8)によって体系的に溶融される方法。

Description
γ=γ0+dγ/dT・T
材料の溶融温度で、温度依存性表面張力γは、表面張力値γ0を有する。温度Tの上昇に伴い、この表面張力γは、張力勾配(dγ/dT)によって変化する。勾配が高いほど、張力勾配を補償する流量が増大する。純金属の場合、張力勾配は負である。これは、言い換えれば、温度Tの上昇に伴い、これらの金属溶融物が表面張力の低下を表すことを意味する。この効果は、表面の温度を調整することによって、所望の丸み半径を達成するために利用される。横行速度、適用されるエネルギーの大きさ、表面でのエネルギーの出力密度分布は、温度を調整するためにすべて利用される。
