摘要
介绍了乌克兰国家科学院超硬材料研究所VPBondarenko教授研究小组开发的一种气相法制备WC粉新技术。该技术不采用固体炭粉为原料,而用CH4为原材料,将W粉经气相碳化后,制得含C量可控制的WC粉末,再经常规压制、烧结后制成硬质合金,产品性能符合前苏联国家标准(GOST)3882—74。并对该技术的生产基本原理、粉末特性、及所制取合金的性能作了重点介绍。
Description is made of a new technology for preparing WC powder by carburizing in a mixture gas medium developed by professor V.P.Bondarenko research group of Institute for Superhard Materials of the National Academy of Sciences in Ukraine.WC powders is prepared with CH_4 as the raw material instead of the solid carbon black powder.Upon gas carburization,C-controllable WC powder is prepared,followed by normal compaction,sintering to obtain cemented carbide.The properties of the alloy products are in accordance with the former Soviet Union State Standard(GOST)3882—74.Description is also made of the basic principle of the technology,powder and alloy properties.
