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 کاملChemico-Thermal Treatment of Titanium Alloys – Nitriding
Titanium and its alloys are widely used in aircraft, rocket production, shipbuilding, machine industry, chemical and food industry, medicine due to their high specific strength, good corrosion resistance and biological passivity. However, titanium has properties which limit its application as construction material. Particularly, tendency to surface adhesion and galling at friction results in it...
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...
متن کاملEvaluation of Plasma Nitriding Efficiency of Titanium Alloys for Medical Applications
Wide use of titanium alloys results from their unique physical and chemical properties 1 . Combination of low density and improved corrosion resistance with good plasticity and mechanical properties determines application of titanium alloys in such industries as aviation, automotive, power and shipbuilding industries or architecture as well as medicine and sports equipment. Despite numerous adv...
متن کاملA Model for Unconventional Glow Discharge Nitriding of Grade 2 Titanium
T. Frączek, M. Olejnik, Częstochowa University of Technology, Częstochowa Poland An analysis of the infl uence of diff erent parameters of the ion nitriding process conducted in a H2 + N2 atmosphere on the properties of the surface layer of Grade 2 titanium was carried out in the study. This allowed a model for ion nitriding of technical titanium to be developed. The equipment used in the exper...
