摘要：

A simple but more efficient technique-high-frequency electropulse deposition-was developed to produce microcrystallized MGH754 ODS alloy coatings on the 1Cr18Ni9Ti stainless steer substrate. The coating has a very fine grain size of 30-300 nm and metallurgical bonding with the substrate. Isothermal oxidation in air at 1 000 degreesC for 100 h shows that micro-crystallisation and dispersed oxide particles promote the selective oxidation of Cr greatly to form a protective and continuous Cr2O3 scale and also improve the scale spallation resistance dramatically, thus increasing the oxidation resistance of 1Cr18Ni9Ti.
