Influence of the Fusing Process on the Wear and Corrosion Properties of NiCrBSi-Coatings
Journal Title: Analele Universitatii "Eftimie Murgu" Resita. Fascicula de Inginerie - Year 2015, Vol 22, Issue 1
Abstract
In this study the NiCrBSi feedstock powder was deposited by flame spraying on to C45 steel substrate. After spraying the coated material was differently fused at 1000°C. The microstructure evolution respectively the phase composition was evaluated by means of scanning electron microscopy (SEM) and by X-ray diffractometry. The corrosion resistance of the differently fused coatings was assessed by potentiodynamic corrosion tests carried out in 3,5 % NaCl solution at room temperature, using a saturated calomel electrode (SCE) as reference. In addition, the variation of the friction coefficients in time for the two tested coatings was determined using the pin-on-disk method. The investigations showed that the characteristics of the inductive remelted coating are better in comparison with the flame fused one.
