Direct nitridation of aluminum compacts at low temperature
Source abstract
Abstract
Direct nitridation of aluminum compacts (relative density 65%)consisting of commercial atomized powder was examined at temperaturesfrom 500 to 700°C, near or below the melting point ofaluminum, and under a pressured nitrogen atmosphere between0.5–7 MPa. Complete nitridation was achieved at a temperature as lowas 540°C by controlling the nitrogen pressure. Thenitridation process and the structures of generated aluminum nitride(AIN) were drastically influenced by nitrogen pressure. Consideringthe relations between the reaction conditions and the reactionprocesses, it is suggested that low nitridation temperature andpre-heating in vacuum have a good effect on the nitridation ratio.
