Ion implantation is a low-temperature process by which ions of one element are accelerated into a solid target, thereby changing the physical, chemical, or electrical properties of the target. Ion implantation is used in semiconductor device fabrication and in metal finishing, as well as in materials science research. The ions can alter the elemental composition of the target (if the ions. During the whole test period, zinc ion implanted pure iron exhibited faster corrosion than the one without ion implantation, and its corrosion rate reached to nearly four times as that of untreated pure iron after 3 days immersion.

Work on the oxidation of Ni, Al, Zr, Ti, Cu and stainless steel has been reviewed by Dearnaley (). This work has been motivated both by the need to improve the corrosion resistance of engineering components, using ion implantation as a versatile method of introducing suitable impurities, andCited by: The influence of ion implantation on the oxidation of nickel and stainless steel.

The purpose of this work was to investigate the effects of the implantation of various metal species upon the high temperature oxidation of polycrystalline titanium and stainless steel.

Oxidation was sometimes enhanced, and sometimes inhibited, to an extent correlated with the electronegativity of the implanted atoms, and increasing with ion by: 2. The influence of cerium and yttrium ion implantation has been examined upon the oxidation behaviour of a 20% Cr/25% Ni niobium stabilised stainless steel.

TiAl-based alloys have attractive properties as light weight heat-resisting material. In the present work, the influence of Cu, Zn, Ag and Se on the oxidation behavior of TiAl was investigated by ion implantation at acceleration voltage of 50 kV and ion doses of to 2x ions/m2.

The oxidation behavior was assessed by a cyclic oxidation test at K in a flow of purified oxygen under. Abstract. The influence of implantation dose on the oxidation behavior of AISI stainless steel was investigated. The steel samples were implanted with Al + ions of energy 40 keV (doses, to 3×10 17 ions/cm 2) and oxidized in air at °C for 48 comparison purposes, samples were also implanted with a dose of 2×10 17 ions/cm 2 of energy keV and treated in a similar way.

Surface treatment by implantation with nitrogen-ion was performed on the commercial feritic high strength steel AISI which is termed for high temperature applications. The aim of this research was focused on the surface modification to improve its high temperature oxidation property in the early stages.

Ion implantation was carried out at acceleration energy of KeV and ion current. Degreasing with solvents, chemical etching, polishing, oxygen and argon plasma treatment and heating and drying produce stainless‐steel surfaces with different amounts of organic contamination and ‘bonded water’.

The hydroxide/oxide layer of the passive film formed on stainless‐steel foils is also affected by surface pretreatment. AISI is a kind of austenitic stainless steel that can be applied for various technologies. Since AISI consists of chromium, nickel, and other materials, understanding the performance of.

Up to now, the three most used metals for implants are stainless steel, CoCr alloys and Ti alloys. The first stainless steel used for implants contains ~18wt% Cr and ~8wt% Ni makes it stronger than the steel and more resistant to corrosion.

Further addition of molybdenum (Mo) has improved its corrosion resistance, known as type stainless steel. For example, ion bombardment 5 and DFR fuel pin data 6 indicate that solution-treated Nimonic PE16 swells less than solution-treated Type stainless steel.

Fuel pin data 7 from EBR-II show that. Metal-ion-induced oxidation. Usually alloys such as stainless steel or nickel-chromium can be used unprotected in innocuous environments and in a certain range of aggressive environments such as seawater or mild acids, depending on the content of alloying elements.

This trend continues as new technologies like ion implantation are. treatments. Rare earth metal ion implantation is very effective for protecting stainless steel and other metals against oxidation at high temperatures.

There are a number of advantages which might be gained if low energy ion implantation treatments could be shown to be effective in modifying the surface mechanical properties of materials. The influence of chemical composition, and temperature on the various physical properties of austenitic stainless steel such as coefficient ofexpansion, thermal conductivity and magnetic permeability is highlighted.

Variation in mechanical properties, such as tensile, fatigue and creep strengths of austenitic stainless steels with temperature.

Surface and Coatings TechnologyOnline publication date: 1-Apr The ion beam technology is mainly based on the production of ionised atoms or molecules, which lend themselves to be accelerated in an electric field.

These ions can be utilized in a variety of ways to either modify or characterise materials. For example, the process of ion implantation is used to create new surface alloys and modify surface.

The continued effectiveness of such approaches, namely by cerium and yttrium ion implantation and with a vapor deposited amorphous silica coating, in reducing oxidation of 20CrNi-Nb stainless steel in a carbon-dioxide-based environment has been examined during and 1more».

Secondly, carbides (WC, TiC, ZrC), Ti, TiN, borides (TiB 2) and silicide (MoSi 2) are considered as a vapour deposited materials and some Cu alloying with Al, N or Mg also considered via ion implantation processes.

But, vapour deposition and. The study groups consisted of four different × inch orthodontic wires 2 cm in length. The 1st group was ion implanted nickel titanium (INT), the 2nd group was nickel titanium without ion implantation (NT), the 3rd group was micro layered esthetic nickel titanium (ENT), and the 4th group was stainless steel (SS) (Table 1).

The purpose of this study is to examine the microstructure and micromechanical properties of pulsed-laser irradiated stainless steel.

The laser marking was conducted for AISI and AISI stainless steel samples through a Nd:YAG ( nm) laser. The influence of process parameters such as the pulse repetition rate and scanning speed have been considered. This investigation was conducted to study on the effect of shot blasting on the case depth of boride layers produced and microhardness after performing paste boronizing on L stainless steel.

micron diameter of glass beads had been used in the process of shot blasting with variation in the blasting pressure. Paste boronizing was performed at °C with 8 hours of soaking time. The relationship between the surface chemistry and the corrosion resistance of electrochemically nitrided AISI stainless steel samples has been investigated.

The nitriding treatment was carried out in HNO 3 M and HNO 3 M + KNO 3 M at room temperature. Samples were subjected to the nitriding procedure for 30 minutes under a cathodic potential of VAg/AgCl.

Ion implantation can improve the properties of the original surface with negligible distortion or oxidation effects, while also producing surfaces with hardnesses between and HV. This results in substantial increases in tool lifetimes, which can reach up to a factor of ten in some cases, for chrome-plated tool surfaces.
