Fig. 5. Time dependences of the friction coefficient and linear wear in friction pairs (a-d) "compact/steel disc", (e-h) "compact/ball made of WC-Co alloy", (k) "coating/ball made of steel" and (l) "coating/ball made of WC-Co alloy"
Under conditions of lubricant-free friction against steel disk, the friction coefficient of compacts 1-4 varies from 0.1 to 0.8. The wear after 10 minutes of testing is small ranging from 2 to 10 µm (Fig. 5, Table 3).
