摘要
选取金属相变材料ZL102作为研究对象,对其进行1200 h的高温抗氧化性试验,并利用XRD、SEM和DSC检测ZL102氧化试样的相关数据。结果表明,ZL102所生成的表层氧化膜主要成分是Al2O3,其具有良好的抗氧化性;氧化1200 h后的ZL102熔化起始温度略增2.4℃,相变潜热下降9.01%,仍具有较好的热物性能。
Cast aluminum 102 was used as one of the metal phase change material,The high temperature oxidation experiment was carried out.The experimental data was measured by XRD,SEM and DSC.This results show that Al2O3 is the main ingredient of the cast aluminum 102 surface oxide film;the oxide film has excellent oxidation resistance.After oxidation at 1200 h,the melting initial temperature of cast aluminum 102 was increased merely by 2.4 ℃;the phase change of latent heat just drops by 9.01%,which indicate that the cast aluminum 102 has good thermal physical properties.
