The compounds of interest in the present study were the natural compounds rutin and quercetin, which are strong antioxidants and have beneficial effects on human health (Myake & Shibamoto, 1997). They are present in everyday foods and beverages and in this way they are used as an integral part of human diet. Therefore, it seemed interesting to investigate the influence of these valuable natural compounds on corrosion processes of aluminium, an ambalage material often used in food industry (Jovanovic et al., 1994). All the investigations were performed in 3% solution of sodium chloride, in aqueous rutin and quercetin solutions as well as in rutin and quercetin solutions in 3% sodium chloride solution. Concentrations of rutin and quercetin solutions used ranged from 10-2 to 10-5 mol dm-3, and investigations involved electrochemical methods. The results obtained showed that rutin and quercetin previously dissolved in 0.1 M NaOH and added to the 3% sodium chloride solution at concentrations of 10-4 and 10-5 mol dm-3 acted as aluminium corrosion inhibitors, while at higher concentrations (10-2 and 10-3 mol dm-3) their effects were opposite. The efficiency of the corrosion inhibition of aluminium by rutin and quercetin solutions was the result of forming protective film on the metal surface. Therefore, the diluted rutin and quercetin solutions could be used as corrosion inhibitors of aluminium.

The chemical and physical processes occurring during the grinding of nickel hydroxocarbonate and mixtures of nickel hydroxocarbonate with aluminium and aluminium oxide were discussed. For mechanical treatment a planetary ball mill was used. The phase analyses of ground products were carried out using thermogravimetry and X-ray diffraction methods. The amount of Ni2(OH)2CO3 undecomposed and Al2O3xH2O, xNiO, Ni0, NixAly alloys and remained Al0 in the systems strongly depends on the proportion of components and on the duration of grinding in a mill which was used in the study. The comparative results are presented.

The chemical and physical processes occurring during grinding of copper hydroxocarbonates mixtures with aluminium were studied.
A planetary ball mill was used. A thermogravimetry and X-ray powder diffraction method allowed to determine the composition
of solid products after mechanical activation. The amount of the Cu2(OH)2CO3 undecomposed andAl2O3⋅3H2O, CuO, Al2O3, Cu0, CuxAly alloys and remained Al0 in the systems is strongly dependent on the duration of grinding and on the proportion of components.
The comparative results are presented.

Metal foam is a cellular structure consisting of a solid metal – frequently aluminum – containing a large (50–99%) volume fraction of gas-filled pores. The pores can be sealed (closed-cell foam), or they
