研究了两种适用于ＰＦＢＣ烟气轮机涡轮叶片的磁控溅射ＭＣｒＡｌＹ涂层的组织和性能．结果表明两种涂层都具有优良的抗高温氧化和抗热腐蚀性能，良好的抗急冷急热性能，涂层与基体合金的结合强度大于７５ＭＰａ
The microstructures and properties of two magnetron sputtered MCrAlY coatings for turbine blades of PFBC flue gas turbine were studied. The results show that both coatings have excellent high temperature oxidation and hot corrosion resistance, good anti-quenching and thermal performance, the bonding strength of the coating and the matrix alloy is greater than 75MPa
