논문 초록 (Abstract)
TZM is a traditional alloy for high temperature applications, in which (Ti, Zr)C particles are dispersed in a Mo matrix. However, due to easy formation of an oxide layer on the TZM alloy under ambient atmosphere, an oxidation protective coating is needed for any high temperature structural applications of TZM. In this study, aluminium pack cementation coatings have been carried out on TZM alloys, resulting in the formation of Al8Mo3 layer on the surface of TZM alloys. In order to examine the oxidation stability, the TZM alloy was exposed in an aerobic atmosphere. For the aluminide coated TZM alloys, an alumina layer was produced at the outer surface layer. The alminide coated TZM alloys showed excellent oxidation resistance. The coating layer kinetics and the corresponding oxidation stability are also discussed in terms of microstructural observations.
