Improving Bond Strenght between Carbon Steel and Plasma Sprayed Ceramics by Phosphating Process
Original language description
Phosphating is currently the highest standard of surface treatment before painting in the vehicle industry. Excluded phosphate crystal layer is due to its high porosity absorbing not only paints but also oil and lubricants that can reliably maintain thesurface. Improved bond strenght in the case of coatings exposed in the humid atmospheres in comparison with multiple non-coated surface. Focus of this work is an effort to improve the bond strenght between the diferent plasma-sprayed coatings materials and carbon steel using different phosphate coatings. Because most of the eliminated phosphate crystallizes with four crystal waters the samples was covered by zinc-calcium phosphate, which crystallizes with only two waters [scholzite: Zn2Ca(PO4)2 . 2H2O]and coated from bath of ?three-cationts? phosphate due to the large thickness of the coating and compaction [fosfofylit: Zn2Fe(PO4)2 . 4 H2O]. They decided test for measuring the quality of bond strebght between coating and steel
