Abstract
Microstructural changes were investigated when nitrogen ions were injected into a WC–Co surface. The crystallographic orientation of WC, relative to the incoming ions, affects the number density and the types of dislocations, but the penetration depth from the accelerated ions was constant regardless of grain orientation. It is believed that the injected nitrogen atoms replaced existing carbon atoms in the highly defective region.
