Title

KINETICS OF VANADIUM CARBIDE COATING PRODUCTED ON DIN 1.2367 HOT WORK STEEL BY THERMO REACTIVE DIFFUSION METHOD

Pages

  81-89

Abstract

 Excellent wear resistance, impact resistance together with good thermal stability of carbide coatings that created by THERMO REACTIVE DIFFUSION (TRD), makes it favorable in technological respect. This research investigated KINETICS of VANADIUM CARBIDE coating on DIN: 1.2367 HOT WORK STEEL. These processes carried out in solid medium containing powders of ferro-vanadium, ammonium chloride and alumina To investigation the KINETICS of these processes, coating layer thickness measured for 0.5, 1.5, 3 and 4.5 hours at different temperatures of 950, 1050 and 1150oC. According to time and temperature, layer thickness obtained between 2.3 to 32.2 X-ray diffraction analyses, optical and scanning electron microscope with EDX spot analyser employed to characterize coating layer properties. Relation between temperature and activation energy obtained as Arrhenius equation and growth rate constant and activation energy obtained, 7.98x10-4 Cm2/s and 173.2 KJ/mol correspondingly. Finally characterized that to obtain minimum porosity in coating layer, processes must carry out in low temperature as far as possible.
