Study of Growth Process for Functionally Gradient Nanocomposite Coating Fabricated by Plasma Electrolytic Carburizing

Abstract:

In this paper, plasma electrolytic carburizing has been applied on the commercially pure titanium substrates in an organic based electrolyte with presence of some hard tungsten carbide nanoparticulates in suspension state. Pulsed current with variable duty cycle has been used for fabrication of functionally gradient nanocomposite coating. As a result, a hard nanocomposite layer has been formed on the surface of the samples with complex titanium carbide as its matrix and tungsten carbide nanoparticulates as its reinforced phase. In addition of used SEM, TEM and AFM for evaluation of coating nature, the presence of tungsten in different depths of formed layer has been followed by means of EDS. The effects of rate of variable duty cycle of applied pulsed current or treatment time have been described. Hardness profiles showed that the higher rates for variable duty cycles will cause lower hardness and sharper profilesThis document explains and demonstrates how to prepare your camera-ready manuscript for Trans Tech Publications. The best is to read these instructions and follow the outline of this text. The text area for your manuscript must be 17 cm wide and 25 cm high (6.7 and 9.8 inches, resp.).
