A novel duplex plasma treatment combining plasma nitrocarburizing and plasma nitriding
Vacuum, 2016Abstract In this study, a novel duplex treatment (DT) combining plasma nitrocarburizing (PNC) and plasma nitriding (PN) was primarily developed for AISI 1045 steel. The modified samples were investigated by optical microscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), microhardness test, and pin-on-disk tribotest.

Microstructure of electroplated hard chromium coatings after plasma nitrocarburizing
Surface and Coatings Technology, 2005Abstract Plasma nitrocarburizing was carried out on the hard chromium coating deposited on SM45C mild carbon steel substrate by electroplating. After plasma nitrocarburizing at 720 °C for 20 h, a 6–7-μm-thick nitride layer consisting of CrN and Cr 2 N was formed on the surface of Cr coating with the microhardness of about 950–1100 HV0.1.

Plasma and gaseous nitrocarburizing of C60W steel for tribological applications
Vacuum, 2009Abstract A comparison has been made between plasma and gas nitrocarburizing processes for C60W steel in terms of structural features of the layers and the tribological properties of the specimens. Gaseous treatments were performed in a sealed quench industrial furnace in optimized process cycles.

Abstract DLC films were produced on nitrocarburized AISI 4140 steel at 110 °C by a pulsed DC PACVD method. Plasma nitrocarburizing (PNC) at 500 °C and 550 °C was used as an intermediate layer. SEM, roughness, micro-Raman spectroscopy and XRD analysis were employed to investigate the microstructure, surface roughness, various carbon phases and ...

Electrolyte–electrode interface and surface characterization of plasma electrolytic nitrocarburizing
Surface and Coatings Technology, 2013Abstract A plasma electrolytic nitrocarburizing (PEN/C) process was performed on the Q235 steel in an aqueous solution of urea to modify the surface properties. The decomposing particles of organic compounds in the electrolyte adjacent to the electrode were obtained using ultraviolet spectrum during the process.
