diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (om), microhardness depth profiling (hdp), scanning electron microscopy (sem), x-ray diffraction (xrd), glow discharge optical emission spectroscopy (gdoes), and secondary ion mass spectroscopy (sims). plasma nitri...

AISI 304 stainless steel is a type of austenitic that contains high percentage chromium and nickel. It one the most widely used grades commonly in variety applications, including kitchen equipment, food processing chemical equipment. versatile material due to its excellent corrosion resistance, durability, non-magnetic properties. Low-temperature processes like ion implantation, plasma nitridin...

Abstract This article presents the effect of an Indirect Plasma Nitriding process on microstructure and properties Titanium Grade- 2 samples manufactured by Direct Metal Laser Sintering Method (DMLS). It was determined, based morphological analysis that physical chemical phenomena occurring at surface during nitriding has a decisive roughening. Phase stress shown nitrided layer produced in pure...

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...

The article presents a selected area of research and development concerning the methods of material analysis based on the automatic image recognition of the investigated metallographic sections. The objectives of the analyses of the materials for gas nitriding technology are described. The methods of the preparation of nitrided layers, the steps of the process and the construction and operation...

We have investigated the possibility of producing a magnetic encoder by an innovative process. Instead of turning grooves in the encoder bar for precise positioning, we incorporated the information in 304L stainless steel by transforming the austenite to martensite after bar extrusion in liquid nitrogen and marking it with a laser, which caused a local transformation of martensite back into aus...
