The Efficiency of Ion Nitriding of Austenitic
M. Ogórek, Z. Skuza, T. Frączek, Czestochowa University of Technology, Czestochowa, Poland The study examined layers were formed on the outer surface of austenitic stainless steel 304 under glow discharge conditions in the low-temperature and short-term ion nitriding. The outer layers analyzed in the work produced in parallel in the classical process of cathode and a novel method of “active scr...
متن کاملNitriding iron at lower temperatures.
The microstructure in the surface layer of a pure iron plate was refined at the nanometer scale by means of a surface mechanical attrition treatment that generates repetitive severe plastic deformation of the surface layer. The subsequent nitriding kinetics of the treated iron with the nanostructured surface layer were greatly enhanced, so that the nitriding temperature could be as low as 300 d...
متن کاملParameter Prediction through Soft PIN System in a Plasma Ion Nitriding Steel Hardening Unit
This paper introduces an excellent merge of Soft computing techniques from Computer Science Engineering, Plasma Technology and Material Surface Engineering. The paper is mainly focused on the Case Based Reasoning (CBR) approach for plasma nitriding process in the prediction of the values of the process parameters for different alloyed steels based on the actual data available from number of hig...
متن کاملSurface 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...
