Surface Modification of Titanium by Plasma Nitriding
A systematic investigation was undertaken on commercially pure titanium submitted to plasma nitriding. Thirteen different sets of operational parameters (nitriding time, sample temperature and plasma atmosphere) were used. Surface analyses were performed using X-ray diffraction, nuclear reaction and scanning electron microscopy. Wear tests were done with stainless steel Gracey scaler, sonic app...
متن کاملDuplex Surface Treatment of AISI 1045 Steel via Plasma Nitriding of Titanized Layer
In this Study, surface of medium carbon steel (AISI 1045) was modified by titanizing followed by plasma nitriding. Titanizing was performed using pack cementation method, in a pack mixture of ferrotitanium, ammonium chloride and alumina, at 1223 K for 45 and 180 min. Plasma-nitriding was conducted at two temperatures of 803 and 823 K for 5 h, in a gas mixture of 75%N2+25%H2. The samples were c...
متن کاملPlasma-surface modification of biomaterials
Plasma-surface modification (PSM) is an effective and economical surface treatment technique for many materials and of growing interests in biomedical engineering. This article reviews the various common plasma techniques and experimental methods as applied to biomedical materials research, such as plasma sputtering and etching, plasma implantation, plasma deposition, plasma polymerization, las...
متن کاملPlasma Modification of Paper by Means of Surface Barrier Discharge
Plasma-enhanced chemical vapour deposition (PECVD) at atmospheric pressure becomes a promising technology. The objective of the present work is to develop technique for deposition of thin films with desired properties on paper surface by means of atmospheric pressure discharge. The depositions were carried out by the means of surface discharge at atmospheric pressure. The films were deposited f...
متن کاملOsteoblastlike cell adhesion on titanium surfaces modified by plasma nitriding.
PURPOSE The aim of this study was to evaluate the characteristics of various titanium surfaces modified by cold plasma nitriding in terms of adhesion and proliferation of rat osteoblastlike cells. MATERIALS AND METHODS Samples of grade 2 titanium were subjected to three different surface modification processes: polishing, nitriding by plasma direct current, and nitriding by cathodic cage disc...
