Expanding Thermal Spray Performance to New Markets and Applications - 2009 International Thermal Spray Conference, ITSC 2009, Las Vegas, NV, Amerika Birleşik Devletleri, 4 - 07 Mayıs 2009, ss.1183-1188, (Tam Metin Bildiri)
In this work, mechanically alloyed Al-12Si/TiB2/h-BN composite powder was deposited onto an aluminum substrate by atmospheric plasma spraying. The results revealed that the mechanical alloying (MA) process has a significant effect on composite powder morphology and in-situ reaction intensity between the selective powders during plasma spraying. In addition, hexagonal boron nitride (h-BN) powder incorporated as a solid lubricant, which has excellent lubricating properties, decomposed into B and N and formed a solid solution after a long period of milling. More specifically, during plasma spraying a large amount of h-BN reacted with Al to form AlN. Unlubricated ball-on-disk testing ring was used to examine the anti wear performance of the coatings. The worn surfaces were examined using scanning electron and energy dispersive spectroscopy to elucidate the wear mechanisms operating at the sliding interface.
