The resistances to wear, corrosion and oxidation of implanted H13 steel using pulsed Ti and Y ions were studied. The Ti and Y ions were produced from a metal vapor vacuum source (MEVVA). The instantaneous beam current was from 0.3 to 1 A and energy was from 25–50 keV. The target temperature was raised to 300°C for a flux of 38 μA cm −2 and to 600°C for a flux of 76 μA cm −2. The hardness of Ti-implanted steel increases with ion dose and decreases with ion flux. The wear resistance of Ti-implanted steel is 3–3.7 times that for the unimplanted steel. Precipitates of Fe 2Ti were observed by X-ray diffraction and high energy electron microscopy (HVEM). The size and amount of Fe 2Ti increases with increasing ion dose and ion flux. The oxidation barrier of Y-implanted H13 steel formed during oxidation at 800°C for 10 min was measured by RBS. The oxidation rate of Y-implanted steel was 8–10 times less than the unimplanted steel. The electrochemical properties of Ti and Y implanted steel in 1 mol H 2SO 4 or solution of NaCl were studied. The results show that the Y implantation is effective for improvement of corrosion inhibition of H13 steel, GCr15 and 304 stainless steel.
