Article Preview

Up to the fourth moment distributions of carbide nanocrystallites, produced by duplex treatments of surface nanocrystallization and pulsed plasma electrolytic carburizing on AISI316 stainless steel, were investigated to high precision by means of figure analysis. A skewness and kurtosis study of the Gaussian distribution has been made, and the effect of an applied voltage has been determined. It is found that the use of higher applied voltages is more suitable for achieving lower sizes of carbide nanocrystallites. The surface roughness of treated samples was measured and it has been observed that there is an optimum level of applied voltage for surface roughness increase (difference between two measured data).
