Effect of germanium oxide on the properties of aluminum casting details in agricultural machinery

Abstract

The article presents research aimed at improving the properties of aluminum alloy by changing its composition when developing a pump housing part that can be made of aluminum alloys in agricultural machines. In the studies, germanium oxide was included in the composition of aluminum-manganese and aluminum-copper alloys, its effect on the alloy structure and hardness was studied. Scientists from all over the world have conducted many similar studies. In the experiments, the composition of the aluminum alloy included Germanium oxide in the charge in the state of coating with a special aluminum coating. Germanium oxide is part of the alloy in an amount from 0.1% to 0.3%, depending on the weight of the charge and taking into account the Germanium content in the oxide. Microscopic analysis of the cast samples was carried out using an optical metallographic microscope. In addition, the hardness of the samples was measured using an ITV-1-M hardness tester. Based on the results obtained, a graph of the dependence of Germanium oxide in the alloy on hardness was developed. Based on the conducted research, the authors draw their conclusions at the end of the article.
