. 2 Experimental The GH128 alloy had the following nominal chemical compositions (mass fraction, %): Cr 22, W 9.0, Mo 9.0, Al 0.8, Ti 0.8, C≤0.05, Fe≤1.0, Zr≤0.06, B≤0.05, Ce≤0.05, Mn≤0.05, Si≤0.08... on Ni-25%Cr (mass fraction) reduced the subsequent oxidation rate at 1 000 ℃ to a similar content to that for implantation into the alloy, but no improvement in scale adhesion. PA?L et al[9] found that Ce......
