Abstract: PROBLEM TO BE SOLVED: To solve such a conventional problem that, although cemented carbide is a high hardness and high toughness material and various trace elements including vanadium carbide (VC) are added to bring out its performances, the grain size of a raw material prepared by pulverizing a carbide become large when the vanadium carbide (VC) is used and, as a result, uniform improvement of properties in a product cannot be done.
SOLUTION: One of component materials of a stock for a tool, such as a hob, is replaced from a carbide to vanadium trioxide (V
2 O
3 ) as an oxide. Since vanadium oxide is softer than vanadium carbide, vanadium oxide can be easily reduced in particle size in a mixing step using a ball mill in the course of raw material blending. The hardness of cemented carbide after sintering can hereby be increased by the effect of the vanadium trioxide uniformly dispersed in the raw material.

解决方案：用于工具的坯料（例如炉刀）的组分材料之一被碳化物替换为三氧化二钒（V 2 SB 3 O 3 / SB 3），作为 氧化物。 由于氧化钒比碳化钒软，所以在原料混合的过程中，使用球磨机的混合工序中的氧化钒粒径容易降低。 因此，通过均匀分散在原料中的三氧化二钒的效果，可以提高烧结后的硬质合金的硬度。 版权所有（C）2009，JPO＆INPIT
