本文主要研究内容
作者刘志学（2019）在《PAG淬火介质淬火冷却性及热化学稳定性研究》一文中研究指出：淬火工艺是产品在热处理过程中获得所需结构和性能最重要的环节之一。由淬火而导致的淬火变形、裂纹、软点、未淬透等缺陷在淬火工件中经常出现。正确使用该淬火介质可以成功解决热处理工艺中,很多形状复杂的工件,用水淬火要开裂而改用油淬火又淬不硬的技术难题。PAG水溶性淬火介质自上世纪90年代引入国内之后,其优异的性能使得工厂大量使用其来替代水和淬火机油。本文对三种PAG水溶性淬火介质:美国进口75-H-380000,韩国进口W55000和自研开发的国产HS牌KLM-165Q的物理化学参数、淬火过程中的热化学稳定性、挥发排放物的环保性能、淬火冷却特性和诱发工件产生裂纹的特性等做了一系列分析,并和常用的水、淬火油等介质做了系统的对比。获得了如下主要结论:(1)三种PAG水溶性淬火介质的诸多物理化学参数相近,热稳定性能相当,其误差变化均较小。(2)淬火油油烟中有害物质的含量明显大于PAG淬火介质,而国产PAG介质中有害物质的含量略高于进口的美国PAG介质。国产和进口PAG水溶性淬火介质都具有良好的环保性能。(3)国产HS牌KLM-165Q PAG溶液的最大冷速在各个浓度下都大于美国和韩国进口的PAG溶液,国产和进口PAG水溶性淬火介质的淬火冷却特性均可在水和淬火油冷却性质之间按淬火工艺要求可控可调。(4)国产HS牌KLM-165Q PAG溶液的使用稳定性随着使用时间的延长而下降,使用18个月后其冷却速度接近自来水的冷却速度,使工件在淬火过程中容易发生淬断的可能性增大。(5)与水淬和油淬比,使用PAG溶液淬火所得的组织结构均匀,马氏体成片层状,完全可以满足淬火工艺要求。所有淬火介质均有诱发裂纹的倾向,只是水淬状态下的裂纹粗壮,扩展较快,PAG溶液及油淬状态下的裂纹细小,扩展较为缓慢。(6)自行开发的国产PAG水溶性淬火介质具有良好的抗老化性和耐用性。完全可以代替进口的同类产品用于生产并投放市场,该产品有着可观的社会经济效益和推广使用前景。
