چکیده انگلیسی
A Zr-doped single-phase (Ni,Pt)Al coating was prepared on a Ni-based single crystal superalloy through electroplating Pt-Zr composite layer and subsequent gaseous aluminisation treatments. Hot corrosion tests of simple aluminide, (Ni,Pt)Al and Zr-doped (Ni,Pt)Al coatings in Na2SO4/NaCl (75:25, wt./wt.) were conducted at 850â¯Â°C in static air. The results indicated that the Zr-doped coating showed superior hot corrosion resistance to both conventional aluminide and (Ni,Pt)Al coatings, in which the enhanced performance is mainly attributed to the advantageous effects of Zr that interacts with S and Cl. The mechanism and role of Zr played in the corrosion test are discussed.
