Abstract Scope |
For various of products made of cast aluminum alloys, such as parts of household appliances contacting with a corrosive environment, the increased corrosion resistance is required. One of the ways to increase the corrosion resistance of aluminum alloys is anodizing. However, anodizing increases the cost of products and it cannot be applied to bimetallic castings. Al-Ca alloys demonstrate good corrosion resistance in as-cast state together with excellent castability allowing to produce parts of complex geometry. In the Al-Ca system alloys, various alloying elements are used to achieve good level of mechanical properties. In this paper, the Al-Ca compositions containing Zn, Si, Fe, Mg and Mn were analyzed in comparison with Al-Si alloys to investigate the effect of these elements on corrosion resistance. It is shown that Al-Ca alloys have a good potential for the applications where high corrosion resistance is a key characteristic. |
