Title: Ion implantation effects on surface-mechanical properties of metals and polymers

Abstract

Fatigue of 8 complex alloys based on Fe-13Cr-15Ni-2Mo-2Mn-0.2Ti-0.8Si- 0.06C, and single-crystal Fe-15Cr-15Ni, implanted with 400-keV B[sup +] and 550-keV N[sup +] (total dose 2.3[times]10[sup 16] ions/cm[sup 2]) was examined. 600 C creep was also examined. The dual implantation increased hardness but decreased fatigue life of the 8 complex alloys. An optimum strengthening level and a shift to grain boundary cracking were determined. The single crystals also showed reduced fatigue life after implantation. High temperature creep of E1 and B1 alloys were improved by the dual implantation. Four polymers (PE, polypropylene, polystyrene, polyethersulfone) were implanted with 200keV B[sup +] to 3 different doses. PS was also implanted with both B[sup +] and Ar[sup +]. Near-surface hardness and tribological properties were measured. The hardness increased with dose and energy; wear also improved, with an optimum dose. (DLC)
