While such substrate coated with sputtered microcrystallized CoCrAl alloy film was not damaged under oxidation even through 100 cycles at 1000℃. In comparison with the normal-grained alloy, the microcrystallized alloy coating of similar constitution exhibite more excellent resistance to oxide spalling on surface. Key words:  microcrystallized CoCrAl coating      cyclic oxidation      sputtering      Received:  18 June 1991      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1991/V27/I6/104 1 Whitle D P, Stringer J.
