本文讨论了功能梯度硬质合金的电泳法沉积。对于WC-Co硬质合金，即使钴粉单独存在时不能从介质中析出，也可以在WC的沉积层中加入钴粉。功能梯度WC-Co硬质合金板材的钴含量梯度从硬面的6w/o到软面的17w/o。为了达到全密度，必须通过固相或液态烧结来烧结沉积。而在1290℃下固相烧结后，钴梯度消失，而钴梯度消失。
Electrophoretic deposition of functionally graded hardmetals is discussed in this paper. With respect to WC-Co hardmetals, cobalt powder can be incorporated in a deposit of WC even though it does not deposit from the medium when present alone. Functionally graded WC-Co hardmetal plates are produced with a gradient in cobalt content going from 6w/o cobalt on the hard side up to 17w/o on the soft side. To reach full density, the deposits have to be sintered either by solid state or liquid phase sintering. Whereas the cobalt gradient was disappeared after liquid phase sintering, it remained after solid state sintering at 1290°C.
