The reaction process usually takes place at lower temperature. For AlN powder, the reaction process is found during oxidation in temperatures ranging from 550 to 1100 °C [8,10,14,16]. For bulk specimens, the reaction process is found in the temperature interval from 1000 to 1390 °C [7,9,11–13, 15].
14 lut 2023 · Here, we characterise the effects of time (up to 12 h) and temperature (490 to 560 ∘C) on nitridation with the aim to establish an effective regimen for the controlled synthesis of an aluminium nitride reinforcement powder for the production of metal matrix composites.
1 cze 2016 · A thin nitride layer containing high amounts of oxygen is formed on the surface of A199.5 treated by Plasma Immersion Ion Implantation (PIII) at temperatures up to 500°C.
13 maj 2024 · Aluminium nitride (AlN) ceramics, which possess high thermal conductivity and electrical insulation, are gradually used in heat dissipation systems for high-power semiconductors. However, oxygen impurity has been one of the key factors limiting the thermal conductivity of AlN ceramics.
Normal plasma nitriding requires long processing time to successfully form AlN layer. For advancing this surface treatment, refining microstructure and micro-alloying processes are proposed to activate the formation of AlN by plasma nitriding.
1 kwi 2017 · The synthesis of aluminum nitride (AlN) powders from aluminum (Al) particles via a thermal nitridation process was carried out at high temperature (>900 °C) with a long reaction time (∼several hours).
1 lip 2016 · In this study, a new nitriding process is proposed to produce the aluminum nitride on the aluminum surface. A process of combined barrel and plasma nitriding techniques was used.
