Nitriding of nanocrystalline iron and reduction nitride with gaseous mixtures hydrogen ammonia were studied at 375 °C atmospheric pressure using the chemical potential programmed reaction (CPPR) method coupled in situ XRD. In this paper, a series phase transitions occurring during processes is shown, detailed analysis composition structure material given. The influence variable nitriding on lat...

AISI 304 SS has good corrosion resistance in a variety of environments but does not have to wear. Aggressive marine require materials that can withstand both the biocorrosion and wear associated with impact waves, ocean currents suspended particles. Oxy-nitriding stainless steels be used increase their hardness resistance. The conventional oxy-nitriding process is lengthy, temperature involved ...

AISI 304 stainless steel categorized under austenitic, has good resistance to corrosion and applicable for high pitting stresses. But it poor hardness, sterngth wear. In order overcome the above problem, various hardening techniques like nitriding, carburizing, carbonitriding, Cyaniding etc are preferred. this work, aqueous soluted nitriding process is carried out improve surface hardness wear ...

The experimental researches on the promotion of new technologies for local protection metallic parts against plasma nitriding, led to two types special paints in ionic elaborated basis copper lamellar powder combination with magnesium oxide and carbon tetrachloride. In created context, it was considered that could be used not only preventing hardening during nitriding certain technological surf...

The article presents a complex system of design, in situ visualization and control of the commonly used surface treatment process: the gas nitriding process. In the computer design conception, analytical mathematical models and artificial intelligence methods were used. As a result, possibilities were obtained of the poly-optimization and poly-parametric simulations of the course of the process...
