Plasma-polymerized acetylene nanofilms modified by nitrogen ion implantation
(2013-06-15)
Thin films were prepared by plasma enhanced chemical vapour deposition (PECVD) from a mixture of acetylene and argon, and post deposition-treated by plasma immersion ion implantation (PIII). The effect of PIII on the ...
The improvement of thin polymer film properties through plasma immersion ion implantation and deposition technique
(2001-12-01)
Thin polymer films were deposited from acetylene and argon mixtures by plasma immersion ion implantation and deposition. The effect of the pulse frequency, v, on molecular structure, optical gap, contact angle and hardness ...
Compressive fatigue in titanium dental implants submitted to fluoride ions action
(2007-07-01)
The aim of this study was to assess the influence of a fluoridated medium on the mechanical properties of an internal hexagon implant-abutment set, by means of compression, mechanical cycling and metallographic characterization ...
Surface modification by metal ion implantation forming metallic nanoparticles in insulating matrix.
(Kusadasi, 2013-09-15)
There is special interest in the incorporation of metallic nanoparticles in a surrounding dielectric matrix for obtaining composites with desirable characteristics such as for surface plasmon resonance, which can be used ...
Effects of Plasma Immersion Ion Implantation (PIII) of nitrogen on hardness, composition and corrosion resistance of Ti-6Al-4V alloy
(2006-09-01)
Ti-6Al-4V samples have been treated by PHI processing at different temperatures (400-800°C), treatment time (30-150 min) and plasma potential (100 and 420 V). Hardness measurements results showed an enhancement of the ...
Synthesis of thermoplastic composites from carbon fibers treated by plasma immersion ion implantation (PIII)
(2012-01-01)
This paper deals with synthesis of thermoplastic composites from CFs treated by PIII processing at different treatment times, 2, 5, 10 and 15 min. The characterization of CFs samples was carried out using the following ...
Two dimensional computer simulation of plasma immersion ion implantation
(2004-12-01)
The biggest advantage of plasma immersion ion implantation (PIII) is the capability of treating objects with irregular geometry without complex manipulation of the target holder. The effectiveness of this approach relies ...
Study of magnetic field enhanced plasma immersion ion implantation in Silicon
(Iop Publishing Ltd, 2014-01-01)
A comparison between experimental measurements and numerical calculations of the ion current distribution in plasma immersion ion implantation (PIII) with external magnetic field is presented. Later, Silicon samples were ...
Preliminary characterization of a Plasma Focus device used as pulsed ion implanter
(2015)
Focus device on a cost effective basis. High energy ion beam emission is one, among several others, of the very interesting transient plasmas phenomena observed in plasma focus discharge. In the last decade the plasma focus ...
Effect of ion irradiation on the structural properties and hardness of a-C:H:Si:O:F films
(Iop Publishing Ltd, 2015-01-01)
Amorphous carbon-based thin films, a-C:H:Si:O:F, were obtained by plasma immersion ion implantation and deposition (PIIID) from mixtures of hexamethyldisiloxane, sulfur hexafluoride and argon. For PIIID the sample holder ...
