Dose effect on mechanical properties of high-energy

In this work, we investigated the influence of nitrogen dose on mechanical properties of 316L stainless steel. Implantation energy was fixed at 1 MeV and the fluence was varied between 5×1016 at Electrochemical and mechanical properties of alloy steels Jul 01, 1991 · The alloy steels 1Cr13, 1Cr18Ni9 and 6Cr3Mo1V were implanted by nitrogen ions (with doses in the range of 5 × 10 16 -4 × 10 17 cm -2 ). Potentiodynamic curves for 1Cr13 and 1Cr18Ni9 steels were measured in a solution of H 2 SO 4 . In the case of 1Cr13 steel the corrosion current was only slightly reduced, whereas in the case of 1Cr18Ni9 steel the corrosion current was reduced greatly. Microstructural and mechanical characterization of Nitrogen ion implantation can be used to improve surface mechanical properties (hardness, wear, friction) of stainless steels by modifying the near-surface layers of these materials. In this study, a medical grade FeCrNi alloy (316L stainless steel plate) was implanted with 85 keV nitrogen ions to a high fluence of 1 × 10 18 N 2 + /cm 2 at a

On the materials properties of thin film plasma-nitrided

The mechanical properties could be adjusted and improved by plasma nitriding conducted at temperatures lower than 450 degrees C and/or nitrogen content less than 10% in the treatment gas. Structure and physical and mechanical properties of heat Aug 23, 2014 · This paper investigates the structural state and physical and mechanical properties of austenitic steel 55Kh20G9AN4 treated with concentrated fluxes of nitrogen ions. It is shown that ion beam treatment of the steel at temperatures of 620870 K is accompanied by the formation of nitrogen-modified layers up to 50 m thick. Ion nitriding at 720870 K leads to the formation of nanosized Surface characterization and biocompatibility of titanium Aug 24, 2012 · A well-known and reliable surface treatment process that can enhance surface mechanical properties of titanium alloys is ion implantation [1921]. As concerns nitrogen implantation, besides the increased surface hardness and wear resistance, this surface modification procedure was associated with improved corrosion resistance . In addition, several in vitro and in vivo studies demonstrated the superior biological performance of nitrogen-implanted

Feb 12, 2007 · Surface mechanical properties, corrosion resistance, and cytocompatibility of nitrogen plasmaimplanted nickeltitanium alloys:A comparative study with commonly used medical grade materials. K.W.K. Yeung. Division of Spine Surgery, Department of Orthopaedics and Traumatology, Faculty of Medicine, University of Hong Kong, Pokfulam, Hong Study the effects of nitrogen ion implantation on Jul 04, 2018 · Nitrogen ions were implanted on the Aluminum Alloy 7075-T6 to study the structural and mechanical properties. The implantation was carried out at energy 1 MeV with ion doses ranging from 8 × 10 14, 1.2 × 10 15 and 5.2 × 10 15 ions cm 2. Structural analysis of all the samples was done by x-ray Diffractometer (XRD) for the implanted ions.
