几十年来,硬质合金一直被用来制作工具、模具和耐磨零件,它已成为我们现代工业经济不可缺少的部分,因为我们天天碰到的许许多多的东西都要用它来加工制造。其技术尽管已经相对成熟,但仍在以相当快的步伐不断发展,最明显的见证就是近年来在牌号、材质、涂层、几何形状及新的应用方面的进展。这些发展趋势同时也为硬质合金市场的扩大带来了美好的前景。 For decades, cemented carbides have been used to make tools, molds, and wear-resistant parts that have become an integral part of our modern industrial economy because so many things we encounter every day are used to manufacture . Although its technology is relatively mature, it is still evolving at a fairly fast pace. The most obvious testimony is the recent progress in grades, materials, coatings, geometries and new applications. These trends also bring bright prospects for the expansion of the cemented carbide market.
