The development and trend of high temperature oxidation resistance coatings on orbit or attitude con鄄
trol rocket engine are revieded . Silicide coatings on Nb alloy have been widely used from 1 960 s. Pt/ Rh alloy and Ir
coating on Re are also applied on thruster chamber and Re/ Ir exhibit good performance above 2 000益, which is con鄄
sidered the best potential material.
