摘要：

This work reports on the use of a depth-sensing technique at loads below 25.6 mN to evaluate properties of implanted M2 steel. Implantations were carried out on polished discs with N+, Cr+ + N+ and Cr+ ions at energies from 25 to 180 keV and total doses above 10(17) ions/cm2. Single and multiple energy implants were carried out to evaluate the effect on mechanical properties of M2 steel by implantation with interstitial and substitutional elements. Nitrogen implantation showed improvements on surface hardness up to about 50% and higher elastic recovery than the substrate material. This can confirm the wear resistance results already obtained on tool steels used in cold forming and the processing of reinforced, plastics. Combination of nitrogen and chromium ions presented similar hardening effects even at greater depths, while implantation of chromium showed only a very marginal improvement in hardness, with limited effect on elastic recovery values. XPS data are also presented to show the chemical effects of the implanted element related to the benefit in properties obtained.
