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.

1050 Aluminum Alloy

The effects of postrolling heat treatment on the mechanical property and microstructure of 1050 aluminum alloy and 304 stainless steel (SS) clad metals were investigated. Clad metals were made by cold rolling after surface treatments of both sheets followed by heat treatment at 500 °C for various annealing times. The effects of transformation of microstructure at the interface on bonding strength are discussed. The initial clad roll bonding of Al/stainless steel clad metal was bonded by mechanical locking at the interface. The protruding stainless steel in the interface is the diffusion route and forms the better joint with aluminum in the annealing process, which results in the enhancement of the bonding strength. Intermediate layers were formed for over 2 h. It resulted in the weakening of the bonding strength and the fracture surface transforms into a brittle structure. As Al/stainless steel clad metals were under 13% reduction ratio, it had the optimum bond strength with a heat treatment for 1 h at 500 °C.
