Surface modification of Ti-4Al-2V alloy by nitrogen implantation
Ti-4Al-2V is a new type of alpha titanium alloy that suitable for the application in high-temperature and high-pressure water/steam environment. Ti-4Al-2V can be used in marine engineering, nuclear power industry. In this paper the surface characterization of the Ti-4Al-2V implanted with 75 keV nitrogen with fluences of 3 × 1017 and 8 × 1017 N+/cm2 is investigated by glancing-incidence XRD, XPS...
متن کاملAntibacterial effect of acrylic dental devices after surface modification by fluorine and silver dual-ion implantation.
The purpose of the present study was to examine the effectiveness of fluorine and silver ions implanted and deposited into acrylic resin (poly(methyl methacrylate)) using a hybrid process of plasma-based ion implantation and deposition. The surface characteristics were evaluated by X-ray photoelectron spectroscopy (XPS), contact angle measurements, and atomic force microscopy. In addition, an a...
متن کاملSurface Modification of Silicone Rubber by Ion Implantation to Improve Biocompatibility
Silicone Rubber (SR) and SR-based materials have been used as medical tissue implants in the field of plastic surgery for many years, but there are still some reports of adverse reactions to long-term implants. In our study, three types of carbon ion silicone rubber were obtained by implanting three doses of carbon ions. Then, the surface characteristics, the antibacterial adhesion properties a...
متن کاملSurface modification of 9Cr18 bearing steels by a metal and carbon co-plasma immersion ion implantation
Ž . In the aerospace industry, 9Cr18 martensitic stainless steel AISI 440 is commonly used as a bearing material. Because of its Ž . ability to rapidly treat irregular industrial components, plasma immersion ion implantation PIII is an effective method to improve the wear resistance of 9Cr18 precision bearings and prolong their working lifetime. Vacuum arc plasma sources provide a good means of...
متن کاملNanoscopic surface modification by slow ion bombardment
We present systematic scanning tunneling microscopy (STM)/atomic-force microscopic (AFM) investigations on nanoscopic defect production at atomically clean surfaces of SiO2, Al2O3 and highly oriented pyrolytic graphite (HOPG) after bombardment by slow (impact energy ≤ 1.2 keV) singly and multiply charged ions under strict ultra-high vacuum (UHV) conditions. Combined STM and AFM studies show tha...
