一般DSC曲线上存在表示玻璃转变的吸热峰和发生晶化的放热峰,但铝基非晶合金的GFA较小,属于边缘性非晶合金,涂层没有明显的玻璃转变温度Tg。涂层的第一放热峰分别始于215.8, 237.6 和236.3℃,表明涂层具有一定的抗结晶性。第一晶化温度较高表明涂层不易发生晶化。如果温度超过200℃,这些涂层会很快结晶,关键性能会恶化。该温度对在工业应用中判断结晶反应和高温稳定性具有重要意义。
The first exothermic peak of the coating starts at 215.8, 237.6 and 236.3°C, which indicates that the coating has some resistance to crystallization. The higher first crystallization temperature indicates that the coatings are less susceptible to crystallization. If the temperature exceeds 200°C, these coatings will crystallize quickly and the critical properties will deteriorate. This temperature is important to determine the crystallization reaction and high temperature stability in industrial applications.
