A study of surface modification of steel, Al alloy by ion implantation technique.

Abstract

The effect on the metallurgical structure and wear behavior of Al-Si alloy and steel produced by nitrogen ion implantation and ion beam mixing deposition (simultaneous nitrogen ion implantation and Ti vapor deposition) using an ion beam source were studied.A combination of X-ray diffraction, Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS) was used to determine the metallurgical structure and chemical composition, and to investigate.The chemical bonding state of the ion treated surfaces.X-ray diffraction data showed that TiN films were formed at room temperature by ion beam mixing treatment.It is demonstrated, that a mixing layer was observed between the substrate and TiN film.AlN was observed when nitrogen ions were implanted in Al-Si alloy. The pin-on disk wear test showed a decrease in the coefficient of friction and an increase in wear resistance for surface treated by both nitrogen ion implantation and ion beam mixing.

X-Ray Stress Measurement and Mechanical Properties of TiN Films Coated on Aluminum and Aluminum Alloy Substrates by Arc Ion Plating and Ion Beam Mixing

“…In order to improve wear properties of aluminum and aluminum alloys, TiN film was deposited with an arc ion plating (AIP) and an ion beam mixing (IBM) methods. (1) The films deposited by the AIP method exhibited high preferred orientation depending on bias voltage; {111} preferred orientation grows as bias voltage increases from 0 to -80V. On the other hand, the films deposited by the IBM method exhibited high {110} preferred orientation regardless of deposition conditions in all cases.…”

“…In this investigation, TiN coatings are tried to deposit on aluminum alloys by an arc ion plating (AlP) method and an ion beam mixing (IBM) method. Although the AIP is often used to coat films on parts with a large and/or complicated shape, there is little examples of TiN coatings on aluminum alloys by the AIP and the IBM methods [1].…”

Partial Lining of Thin Foils to Metal Surface Using Shot Peening

“…However, these processes are not easy to bond to the limited surface, and a brittle intermetallic compound appears around the bonding interface under hot working conditions. On the other hand, Plating, PVD and CVD are generally employed as the partial lining processes [2]. These lining processes, however, are inadequate for the use under severe conditions because of thin plating layers.…”
