The variations of stainless steel cathode temperature (Tc) as a function of nominal plasma power (driven by discharge frequency) and duty cycle at different pressures (0.6-3.2 torr) in nitrogen plasma are reported in conditions favourable for plasma nitriding. Above power at 200 kHz, it is found that increase in power does not have any significant effect on Tc. Corresponding optical emission sp...

Low temperature plasma assisted nit riding treatments of 316 stainless steel produce a complex layer constituted by tow different metastable f.c.c. solid solution denoted ( γ N1 and γ N2 ). About the formation of these double layers, different hypothesis was proposed in the literature. For verifying these hypotheses, the effects of differentes conditions such as nit riding temperature, cleaning...

Spheroidal graphite cast iron is a material with wide range of uses such as in automobile parts. By applying active screen plasma nitriding (ASPN) treatment, the use spheroidal expanded, and it can be expected to used under special load conditions. In this study, we evaluated effect ASPN treatment on mechanical properties iron. With nitride layer was formed sample surface diffusion further insi...

One of the major issues required to be dealt with the casebased reasoning (CBR) is the challenge to meet to maintain and control the correctness and accuracy of the results expected to be produced against the proposed algorithm and methodology for the candidate CBR system. This paper introduces a computational model with the assistance of the concept of Regression fitting within the mathematica...
