摘要

Quasicrystalline materials (QCs) have very interesting properties which make them good candidates to be used as coatings resistant to wear,high temperature oxidation,corrosion,etc.the potential applciation of Al_71co_13Fe_8Co_8(QC1),a quasicrystalline approximant alloy,as a thermal barrier coating (TBC) for components of aeronauticla and power generation turbines was explored in our laboratories and the results are presented in this paper.QC1 is stable at 1000 deg C and has a thermal conductiviyt similar to that of yttria stabilized zirconia (YSZ),the most commonly used material for TBCs.QC1 powders were low pressure plasma sprayed on IN 100 superalloy and coatings of excellent quality were obtained after a series of optimizaiton experiments.
