ABSTRACTTo measure the mechanical properties of ion implanted layers special microhardness tests with penetration depths less than 100 nm have been made. The results show that increases in hardness of up to 50 % may occur in a number of metals as a result of nitrogen ion implantation. Considerable carbon is also present in the implanted surfaces and when in the form of a distinct layer, may give an apparent softening of surfaces at high doses.

Functionalized Surface

A functionalized surface nanolayer less than 200 nm in thickness was prepared by nitrogen ion implantation at fluences of 2·1017, 4·1017, and 6·1017 cm-2 and at an accelerating voltage of 90 kV on the Ti6Al4V alloy. The evolution of the surface mechanical properties and the structural mechanism of the hardening were investigated. X-ray diffraction showed a great number of αTi+N interstitial nitrogen atoms and finely dispersed TiN precipitates in the modified surface nanolayer. The functionalized surface nanolayer on the sample with applied fluence of 2·1017 cm-2 had a predominant amount of αTi+N of about 45 wt% with minority TiN compound up to 20 wt%. The TiN content increased dramatically with increasing fluence of the implanted nitrogen. Nanoindentation investigations found that the indentation hardness improved up to 408% and that the reduced elastic modulus was increased up to 140%. The main hardening mechanism varied with the nitrogen concentration. Nitrogen ion implantation at low fluence of 2·1017 cm-2 led to a functionalized surface nanolayer in which the hardening was mainly caused by the microstrain due to the large amount of interstitially located nitrogen. Applied fluences of 4·1017 and 6·1017 cm-2 increased the content of TiN compounds, which became the predominant hardening mechanism.
