摘要
以M951镍基高温合金为对象,研究了Al-Si涂层和M 951合金在Na2SO4+25%K2SO4和Na2SO4+25%Na Cl盐溶液中的热腐蚀行为。结果表明,Al-Si涂层的存在可以减少M 951合金的热腐蚀。Al-Si涂层和M 951合金在Na2SO4+25%K2SO4盐溶液中的热腐蚀程度相对较小。
The hot corrosion behavior of M951 nickel base superalloy and Al-Si coating in Na2SO4+25% K2SO4 and Na2SO4+25% NaCl salt solution was studied. The results show that the hot corrosion of M951 alloy is reduced due to the existence of Al-Si coating. And hot corrosion degree of M951 nickel base superalloy and Al-Si coating is relatively small in Na2SO4+25% K2SO4 salt solution.
