AB  - The paper deals with the application of different types of surface preparation before the formation of glued joints made of the same and different steels. Iron phosphate, chromate-free passivation and an experimental preparation based on organosilane were tested. Deep-drawn uncoated steel DC04 and HSLA galvanized steel HX340LAD+Z were joined by adhesive bonding. When applying all types of surface preparation, the joints´ strength was achieved at least at the level of the yield strength of weaker material (DC04). Surface preparation with organosilane leads to a bond strength that is close to the yield strength of a stronger material (HX340LAD+Z) and, therefore, can be recommended for bonding of steels with higher strength.
