Surface Hardening of Cu Alloys by Plasma Nitriding Process.

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...

Chemico-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...

Gas Nitriding of Iron-Based Alloys

The precipitation of tungsten nitride upon internal nitriding of ferritic Fe0.5 at.% W alloy was investigated at 610 °C in a flowing NH3/H2 gas mixture. Different tungsten nitrides developed successively; the thermodynamically stable hexagonal δ-WN could not be detected. The state of deformation of the surface plays an important role for the development of tungsten nitride at the surface. The m...
