AbstractThe Al/hBN composite coatings were fabricated by atmospheric plasma-spray technology, which were used as an abradable sealing coating for aircraft turbo engines. The Al/hBN composite powders were prepared by spray granulation with polyvinyl alcohol binder (ZLPC), spray granulation with sodium silicate binder (ZLSC), and cladding with sodium silicate binder (BFSC), respectively. Microstructures, phase compositions and mechanical properties of the coatings were tested. The results show that the most amounts of AlN and AlB2 are formed in ZLPC type coating. While a little of AIN and AlB2 are formed in ZLSC type coating. In BFSC coating, AIN and AlB2 phases can not be found. The Rockwell hardness and adhesional strength of the coatings increase in order of ZLPC, ZLSC and BFSC type coatings. While the erosion mass loss of the Al/hBN coatings decrease in order of ZLPC, ZLSC and BFSC type coatings, which may be related to the increase of Rockwell hardness of the Al/hBN coatings.; The Al/hBN composite coatings were fabricated by atmospheric plasma-spray technology, which were used as an abradable sealing coating for aircraft turbo engines.
