本文是Fe—Cu—C系圆锥压坯组合的一种新尝试。压坯分为内坯和外坯,将预烧后的压坯在一定的压力下压配,然后在一定的温度下烧结。这种压配的预组合件在烧结后可获得较高的结合强度。选用海绵铁粉,其化学成分及物理机械性能见表1 This article is a new attempt to combine Fe-Cu-C conical compacts. Compaction is divided into blanks and blanks, the pre-calcined compacts under pressure at a certain pressure, and then sintered at a certain temperature. This press-fitted pre-assembly gives a high bond strength after sintering. Selection of sponge iron powder, its chemical composition and physical and mechanical properties in Table 1
