对镍取代或者部分取代WC—Co硬质合金中的粘结相及用镍粘结TiCN金属陶瓷过去已有不少的研究报道和评述。一般认为WC－Ni硬质合金具有与WC－Co硬质合金相同的抗弯强度，但其硬度要低100～200HV。钴相具有较高的加工硬化速度，而镍具有较好的断裂韧性。但是在镍中加入0．5％的铬?
There have been many reports and reviews of the nickel-substituted or partially-substituted binder phase in WC-Co cemented carbide and the nickel-bonded TiCN cermet. It is generally believed that WC-Ni cemented carbide has the same flexural strength as WC-Co cemented carbide but its hardness is as low as 100-200HV. Cobalt phase has higher work hardening rate, while nickel has better fracture toughness. But add 0.5% chromium in nickel?
