Název v původním jazyce
On the effect of multiphase microstructure of ZnAlMg substrate on the Tibased activation and phosphate conversion coating distribution
Popis výsledku v původním jazyce
"The impact of multiphase microstructure of ZnAlMg coatings on the homogeneity of the surface activation and phosphate conversion coating (PCC) is considered. Three ZnAlMg coatings and three pure phases (Zn, Zn2Mg and ZnAl) relevant for these coatings were characterized after Ti-based activation and after the complete PCC procedure. Highly alloyed ZnAl and Zn2Mg were more sensitive to the ageing of the activator bath than Zn. X-ray photoelectron spectroscopy demonstrated that Ti concentration on the surface after Ti containing activation step decreased in order Zn > Zn2Mg≫ZnAl and that TieO group is chemically bonded to the Zn surface while for the alloyed phases mainly TiO2 was formed. Scanning electron microscopy demonstrated that for the coatings with a fine microstructure the complete covering by PCC was achieved in standard conditions despite the differences in the activation state of different phases and different kinetics of PCC formation. This was explained by the hypothesis that the variance in the reactivity of different phases forming the coating can be leveled by the phosphate crystal size, exceeding the substrate microstructure inhomogeneity."
