Abstract
The paper deals with the monitoring the utility properties of
the Al-Si coating which is applied by means of the hot dip
coating on the ultra-high strength sheet 22MnB5 (martensite
steel alloyed by boron). These sheets are used at the car-body
design as the safety elements (bumpers, reinforcement posts).
Individual parts are jointed also by the adhesive bonding
methods. Evaluation of the material surface protection layers is
carried out in dependence on the time of material heating in
the furnace during thermal treatment and subsequent
influence of this layer on the adhesive joint strength and failure
pattern. To compare adhesive joint strength is used epoxy
adhesive from two producers. Results provide information
about behavior of the ultra-high strength sheets adhesive joints
strength properties as a criterion for suitability to apply
coatings AlSi in the series production of cars.
