摘要：

RF precursor plasma spray synthesis (RFPPS) is an innovative and rapid technique to deposit functional oxide coatings by starting from liquid inorganic precursors and directly producing ceramic coatings. RFPPS offers excellent opportunities in exploring the nonequilibrium phase evolution during plasma spraying of molecularly mixed precursors to form multicomponent oxides. A detailed discussion of progress, critical issues and consideration in precursor development, RF plasma spraying, coating development, and phase evolution of yttrium aluminum garnet (YAG) is presented as a case study. Appropriate selection of precursors and proper tuning of spray parameters resulted in amorphous or crystalline coatings in the as-sprayed condition. YAG phase selection has also been investigated using a discrete, low-density combinatorial synthesis approach.
