摘 要:本文基于中国专利检索数据库,通过统计采用熔炼法制备镍基高温合金的在华专利申请趋势、申请人的类型及地域分布特点,分析熔炼法各技术分支的研发现状及发展趋势。分析结果表明,单熔法作为基础制备方法,其专利最多,主要从熔炼工艺、熔炼部件两方面来提高熔体的纯净度,近年来采用复合技术手段提高镍基高温合金的纯净度成为主要的研发方向;双联法制备镍基高合金呈现产业化的趋势;三联法熔炼在我国也将呈现高速的发展趋势。Based on the Chinese Patent Retrieval Database, this paper analyzed the current situation and development trend of the technical branch of smelting method through the statistics data of the patent application trend, applicant type and geographical distribution characteristics of nickel-based superalloy prepared by smelting method in China. The result of the analysis showed that, as basic production method, single smelting method had the most patents, which mainly focused on improving the purity of melt from two aspects namely smelting process and smelting equipment;in recent years, improving the purity of melt via adapting combined technical means become the major research direction;The nickel based high temperature alloy produced with double smelting method has shown a trend of industrialization and triple smelting method will be developed at high speed in China.
关 键 词:熔炼 镍基高温合金 单次熔炼 双联法熔炼 三联法熔炼 专利
