Effectiveness of intraoral suction systems and aspirating tips for evacuation of aluminum oxide particles during use of air-abrasion
(2010-04-01)
Aim: The purpose of this study was to compare the effectiveness of a high-volume evacuation and a conventional intraoral suction system and aspirating tips for capturing aluminum oxide particles during use of an air-abrasion ...

Anodization mechanism on SiC nanoparticle reinforced al matrix composites produced by power metallurgy
(Mdpi Ag, 2014-12-01)
Specimens of aluminum-based composites reinforced by silicon carbide nanoparticles (Al/SiCnp) produced by powder metallurgy (PM) were anodized under voltage control in tartaric-sulfuric acid (TSA). In this work, the influence ...
Densification of lightweight aluminum borate ceramics by direct sintering of milled powders
(Taylor & Francis Ltd, 2018-10)
Dense aluminum borate (Al 18 B 4 O 33 ) materials were processed by simple milling-sintering of aluminum borate powders obtained by reacting calcined alumina and fine boric acid at temperatures of around 600–800ºC. The ...
Cold spray aluminum–alumina cermet coatings: effect of alumina content
(Springer, 2018)
Deposition behavior and deposition efficiency were investigated for several aluminum-alumina mixture compositions sprayed by cold spray. An increase in deposition efficiency was observed. Three theories postulated in the ...

Sinterização reativa do óxido de alumínio processado por manufatura aditiva
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2017-08-18)
The additive manufacturing, especially the binder jetting principle, is capable of producing ceramic parts of complex geometries with low drawability, which is difficult to obtain through other forms of processing. The ...
