Abstract
It has been shown that the residual tensile stresses around Vickers in dentations cause stress corrosion cracking when WC-6wt% Co is exposed to hydrofluoric acid vapour. This investigation was aimed at determini ng whether the compressive surface stresses induced by ion implantatio n could inhibit this type of stress corrosion cracking. The investigat ion was based on implantation of N+ ions at doses ranging from 10(16) to 5 x 10(17) ions/cm(2) at 100 keV. It was found that ion implantatio n does inhibit this type of stress corrosion cracking and that the inh ibiting effect increased with increasing ion dose in the above range.
