TN85系列轻质硬质合金 TN85 series

传统概念上的硬质合金是由难熔金属碳化钨（wc）为硬质相，金属钴（co）或镍（ni）为粘结相的烧结合金材料。wc-co（ni）类硬质合金具有一系列优良性能，其主要是具有较高的硬度和耐磨性，使其在现代工具材料，耐磨材料方面占据重要地位。但是wc-co（ni）类硬质合金也有其自身不足，尤其是粘结相为co的硬质合金，抗高温，耐腐蚀性能较差，从而限制了该类合金在某些工矿领域的应用。tn85系列轻质硬质合金就是针对wc-co（ni）类硬质合金某些性能之不足和在特殊工矿领域中的应用而研制开发的一种新型硬质材料。 the cemented carbide comprised of carbide（wc）and bonding （co or ni）in traditonal concept. this hardmetal has series of perfect properties. especially in hardness and wearing resistance，it has a important role in concept of modern tool materials and wearing materials.however，this hardmetal also has self-weakness,especially in high-temperature resistance and corrosion resistance which composed of bonding（co）that restricted their application in some industrial fields. tn85 series light cemented carbide is the late-modern hard material which make up the self-weakness of wc-co(ni) hardmetal and application in special fields.
