Description
具体的には、ジェットエンジンや産業用ガスターンビンなどのタービン動翼やタービン静翼として高温、高応力下での使用を目的としたもので、部材の耐酸化性、耐高温腐食性などの耐環境特性を向上させることはもちろん、従来技術では解決し得なかった高温での長時間の耐久性を飛躍的に向上させたところにその最大の特徴を有する耐熱部材を提供するものである。
<1>コーティング層は、所定温度において、γ相、γ’相およびB2相のうちの少なくとも1種を含んでいること、
<2>基材の界面近傍において、拡散変質層の生成が抑制されていること、特には、基材のγ相とγ’相との二相構成からの単相の生成や、第三相の析出、あるいはγ’相の存在量の変化としてある変質層の生成が抑制されていることの少なくともいずれかであると定義することができる。
以下に、実施例を示しつつ、本願発明のNi基超合金について説明する。
本出願人が既に出願済みの第4世代のNi基単結晶超合金(TMS−138A)を実施例の合金基材として選択し、真空溶解炉を用いて溶湯の合金組成の調整を行い、Ni基単結晶超合金インゴットを鋳造した。鋳造した合金組成を表1に示す。また、EQコート層に用いられる合金のインゴットも同様に作製し、作製したインゴットの組成を表1に示す。EQコート層に用いられるインゴットのベース合金組成は、第4世代のNi基単結晶超合金(TMS−138A)のγ’相の組成を基本とするものであるが、元素として非常に高価なReおよびRuを合金成分から除いたものである。本願発明のコート材は、このベース組成のEQコート材(EQC)にPtおよびIrを5質量%添加したものであり、上記と同様な方法でインゴットを作製した。
