摘要
本文对铁基合金镀镍渗铝或镀镍后铬铝共渗进行了试验研究。结果表明:不论在抗氧化、抗熔盐腐蚀,还是在抗冷热疲劳性能方面都有明显的改善,并且有良好的抗集碳性能。
A study of aluminizing or chrome—aluminizing the nickel—plated substrat of Fe—base alloy has been performed. The results have shown that the properties of treated gas—turbine blades such as resistances to oxidation, melten salt attacks and thermal shocks were improved obviously . In addition, they offer a good resistance to carbon collection.
