一、技术水平 QPQ盐浴复合处理是国外最新金属盐浴表面强化技术,其技术核心——无公害的盐浴配方多年来一直由德国迪高沙公司(Degussa)独家垄断,且极为保密。美国通用电器、德国大众、日本丰田、本田、日产等一些著名大公司都从Degussa公司引进技术。我国戚墅堰机车厂等几家工厂也曾以60～88万美元从德国引进这项技术,但该公司不提供盐浴配方,因此必须长期高价向该公司购盐。 机械工业部成都工具研究所李惠友、罗德福、林训华、周卫宁等同志经8～9年的刻苦试验研究,不仅独立开发了成分独特的无公害QPQ盐浴配方,而且对渗层形貌、工艺参数、渗层性能等进行了系统试验,开发了系列成套专用设备,进行了大量生产应用和成套技术转让,取得了很好的经济效益和社会效益。
First, the technical level QPQ salt bath complex treatment is the latest metal salt bath surface strengthening technology, its technical core - pollution-free salt bath formula over the years has been exclusive by the German company Degussa (Degussa), and very confidential. Some famous big companies such as General Electric of Germany, Volkswagen of Germany, Japan Toyota, Honda, Nissan and so on have all imported the technology from Degussa Company. China’s Qishuyan Locomotive Works and other factories have also been 60 to 88 million US dollars from Germany to introduce this technology, but the company does not provide salt bath formula, it must be long-term high price to the company for salt. Chengdu Institute of Tool Industry, Ministry of Machinery Industry Li Huiyou, Rod Laver, Lin Xunhua, Zhou Weining and other comrades after 8 to 9 years of hard experimental study, not only the development of a unique composition of pollution-free QPQ salt bath formula, and the infiltration layer morphology, process parameters , The permeability of the performance of a systematic test developed a series of complete sets of special equipment, a large number of production applications and complete sets of technology transfer, and achieved good economic and social benefits.
