本文介绍了以聚二醇为基础,加入微量TPN添加剂的PQA水溶性淬火介质。通过对PQA淬火剂的冷却性能和工艺性的研究,证明以一定浓度的PQA取代水和淬火油,可获得满意的淬火效果。
In this paper, we introduce PQA water-soluble quenching medium based on polyglycol and adding trace TPN additives. By studying the cooling performance and processability of PQA quenching agent, it is proved that the quenching effect can be obtained with a certain concentration of PQA instead of water and quenching oil.
