1990年6月9日,联邦德国德固萨(Degussa AG)公司在北京国际展览中心举办了热等静压(HIP)技术报告会,机电部科技情报研究所组织全国有关粉末冶金及烧结设备单位参加了这次报告会。 传统HIP技术的主要问题是,当处理硬质合金时会造成WC晶粒的长大和破坏表层,而WC晶粒的长大会成为材料断裂的发源地,使其强度和硬度降低,另外,HIP技术所使用的氩气中含有O_2、H_2O、CO_2、
On June 9, 1990, the Federal Republic of Germany Degussa AG held a report on the HIP technology at the Beijing International Exhibition Center. The Institute of Scientific and Technical Information of the Ministry of Machinery and Electricity organized the national units related to powder metallurgy and sintering equipment Attended the report. The main problem of the conventional HIP technology is that the WC crystal grain grows and destroys the surface layer when processing the cemented carbide, and the growth of the WC crystal grain becomes the cradle of the material fracture, so that the strength and the hardness decrease. In addition, the HIP technology The argon used contains O_2, H_2O, CO_2,
