硬质金属

硬金属被广泛的用于安装工具,机械零件,冲压配件和耐磨件。

作为合成材料,这类材料的特点在于它具有金属的特性和独特的化合物的硬度和柔韧性。一般来讲,硬金属由90~94%的硬但又易碎的碳化钨或者其他碳化物,以及6~10%具粘合功用或耐用成分的钴、镍或铁组成。

These relatively soft, ductile, low-melting-point binding agents represent the so-called fluid binding phase in which the carbide material particles are wetted during sintering.

The binding agent permeates the agglomerated particles, compacting the body through contraction of the hard materials (shrinkage) down to the smallest possible size. The hard metal carbides are surrounded by the binder metal matrix but remain separate heterogeneous metallographic constituents. In recent years hard metals have been greatly enhanced and, through new applications and continuous improvement in quality and production technology, have proven their high level of performance. This of course also increases the demands made on processing and production.
