Abstract

In the present study, VC coatings on AISI D3 steel were processed by pack method thermo-reactive diffusion method (TRD) in a solid medium for 2 and 4 h at 950, 1000, 1050 and 1100 °C, respectively. Then, the coated specimens were characterized by scanning electron microscopy, energy dispersive X-ray spectrometry and X-ray diffraction analysis. From the results, between 5.6 and 26.8 μm carbide layers on the surface were obtained by increasing process time and temperature. The coatings were determined by VC and V2C phases. The kinetics of vanadium carbide coating was also studied and the activation energy was estimated to be 180.73 kJ/mol. The avarage value of the microhardness of the coating is 2400 HV. The ball crater test was applied to determine the micro abrasion behaviors of the coated samples.

Kurzfassung

In vorliegender Untersuchung wurden VC-Beschichtungen mithilfe der thermoreaktiven Diffusion (TRD) im Packverfahren in einem festen Medium 2 bzw. 4 h lang bei jeweils 950, 1000, 1050 und 1100 °C auf AISI D3-Stahl erzeugt. Dann wurden die beschichteten Proben mittels Rasterelektronenmikroskopie, energiedispersiver Röntgenspektrometrie und Röntgendiffraktionsanalyse charakterisiert. Durch Verlängerung der Verarbeitungszeit und Erhöhung der Verarbeitungstemperatur konnten auf der Oberfläche Hartmetallschichten einer Dicke von 5,6 bis 26,8 μm erzeugt werden. Die Schichten wurden als VC- und V2C-Phasen bestimmt. Außerdem wurden die Kinetiken der Vanadiumcarbidschichten untersucht. Die Aktivierungsenergie wurde mit 180,73 kJ/mol beziffert. Der durchschnittliche Mikrohärtewert der Beschichtung liegt bei 2400 HV. Im Kalottenschliffverfahren wurde das Mikroabrasionsverhalten der beschichteten Proben ermittelt.
