摘要: Abstract Al 2 O 3 –ZrO –Pt composite coatings were prepared by cathode plasma electrolytic deposition (CPED) on the TiAl alloy. Such can improve cyclic oxidation resistance of alloy effectively. The beneficial results be attributed to effects: such inhibit further substrate owing its extremely low oxygen diffusion rate, possess excellent mechanical properties stress relaxation caused phase transformation zirconia, and toughening role Pt particles. In addition, as polyethylene glycol (PEG) is added in solution during CPED process, current density reduced significantly, would a promising technique deposit uniform large-sized samples.
