This study brings new pieces of knowledge about a utilization of an inorganic filler in an area of steel adhesive bonds exposed to a degradation environment. The filler in the form of glass beads with a fraction size 90 ± 20 μm was used within the research. The aim of the research was to evaluate an influence of the degradation environment on a strength of structural two‑component epoxy adhesives and a composite material. A preparation of adhesive bonds and a process of testing of the adhesive bonds were in accordance with the modified standard ČSN EN 1465. The degradation environment in a form of 5 % saline solution was used within this experiment. Adhesive bonded testing samples were subjected to a cyclic loading of the saline solution. The adhesive bonds with the filler reached up to 16 % higher adhesive bond strength than the unfilled adhesive bonds. The bonds adhesive bonded with the tested composite adhesive better resisted to the degradation process of ca. 9 %. The cyclic exposure, i.e. dipping of the testing samples into the saline solution and consequent drying significantly decreases the strength of the adhesive bond (up to 67 % in 6 weeks).

The paper deals with the monitoring of utility properties of new coating type on the basis of Zn/Mg (ZM). For the comparison there was used commonly used coating in the series production of car-body panels on the basis of zinc (Z100). Measured results markedly contribute to improve production systems of car-body adhesion bonding on the basic of performed evaluation of applied coatings types utility properties quality with regard to influence of temperature and corrosion environment. Testing was carry out by T-peel test acc. to ISO 11339 when such type of loading represents crucial bonding fracture type. Thus results reveal information about behavior of adhesive joints strength properties together with the type of fracture as a criterion for suitable application of new coatings types on the basis of Zn/Mg and their implementation into series production of automobiles.

In this paper the mechanical behaviour of structural two-component epoxy adhesives in T-joints is experimentally investigated. The aim of this study is to analyse the impact of the adhesive bonded surface treatment on the maximum force required to cause destruction, i.e. bearing capacity of T-joints bonded with various adhesives. Experimental results showed that the type of the adhesive aff ected the limit values of a force required for the destruction of the adhesive bond. The eff ect of the bonded surface treatment was also confi rmed. From the results of experiment it was proved on fi ve tested two-component epoxy adhesives that the negative eff ect of the peeling forces can be reduced by mechanical treatment of the adhesive bonded surface e.g. blasting. When there is applied an unsuitable mechanical treatment of adhesive bonded surface, the decrease of the force required for the destruction of the bond was up to about 98%.
