    • A method is provided for producing a sealing segment for use in compressor and turbine components, by powder injection molding, the method comprising the following steps: a) preparing a first homogeneous mixture of a metal powder or a mixture of metal powders or a ceramic powder or a mixture of ceramic powders and at least one binding agent; b) producing a first molded article by injection molding the first mixture; c) preparing a second homogeneous mixture of a metal powder or a mixture of metal powders or a ceramic powder or a mixture of ceramic powders and at least one binding agent, the second mixture being selected to exhibit a lower abrasion resistance than the first mixture following a subsequent joint sintering process; d) producing a second molded article as a rub strip by injection molding the second mixture; and e) joining the first and second molded articles to produce the sealing segment. A sealing segment is also provided for use in compressor and turbine components, composed of at least one first molded article as a base element and at least one second molded article having lower abrasion resistance than the first molded article, as a rub strip, the first and the second molded articles each being produced by powder injection molding.
    • 提供一种通过粉末注射成型制造用于压缩机和涡轮机部件的密封段的方法,该方法包括以下步骤:a)制备金属粉末或金属粉末或陶瓷粉末的混合物的第一均匀混合物 或陶瓷粉末和至少一种粘合剂的混合物; b)通过注塑第一混合物制备第一模塑制品; c)制备金属粉末或金属粉末或陶瓷粉末或陶瓷粉末和至少一种粘合剂的混合物的混合物的第二均匀混合物,选择第二混合物以显示比第一混合物更低的耐磨性 随后的联合烧结工艺; d)通过注射第二混合物制备作为摩擦条的第二模塑制品; 和e)连接第一和第二模制品以产生密封段。 还提供一种用于压缩机和涡轮机部件的密封部分,其由至少一个第一模制品作为基础元件和至少一个具有比第一模塑制品低的耐磨性的第二模制品作为摩擦条,第一 并且第二模制品各自通过粉末注射成型制造。
