针对铝合金淬火使用聚合物淬火剂进行了实验研究.配制了聚合物体积分数为16%和33%的淬火水溶液,选择典型材料和零件进行了一系列对比实验.结果表明:采用33%和16%两种体积分数的AQ251聚合物淬火剂得到的拉伸性能、电导率和耐蚀性与水淬比较无明显差别,处于同一水平;在聚合物冷却介质中淬火可以显著减小零件变形.
The research of using the polymer glycols quenching medium in heat treatment of Al alloy was discussed. The water-polymer glycols quenching solution of concentration 16% and 33% were prepared. A series of comparative tests were carried out by using typical aluminum alloys and parts. The results show that the tensile performance, conductivity and corrosion resistance after heat treatment using polymer glycols quenching medium are in the same lever compared with quenching using water. Deformation of parts obviously decreased after quenching by using polymer glycols quenching medium.
