DZ125合金HY3涂层防护性能研究

Study of Protective Performance of HY3 Coating on DZ125 Superalloy

研究了ＤＺ１２５合金ＮｉＣｒＡｌＹＳｉ防护涂层抗氧化抗腐蚀性能。试验表明，在１１００℃循环氧化加速试验条件下及１０５０℃循环氧化长寿试验中，涂层对合金起到了很好的防护作用，在９００℃燃气热腐蚀条件下，ＮｉＣｒＡｌＹＳｉ涂层明显提高了ＤＺ１２５合金的抗热腐蚀能力。

Resistance to oxidation and corrosion of NiCrAlYSi coating on DZ125 super alloy is researched in this paperThe results show that the NiCrAlYSi coating has good protective performance of DZ125 superalloy against cycling oxidation at 1100℃ and 1050℃ and can enhance property of DZ125 superalloy against gas hot corrosion resistance at 900℃ 
