One of the biggest challenges that engineers encounter in a variety of industry sectors is corrosion. The current research focuses on the corrosion behavior of various types of aluminum alloys widely used in the industry. In this regard, aluminum alloys Al2024, Al6061, and Al7075 were tested. Also, the effect of environmental temperature on the corrosion rate of each group of materials was investigated. Three statistical parameters, including total corroded area, corrosion rate (total corroded area to total sample area), and the maximum size of corroded point, were measured as corrosion indicators in the samples. In addition, the surface hardness of the samples was measured and presented by the Brinell method. Finally, the weakest aluminum alloy against corrosion under different temperature conditions was introduced. The corrosion test conducted in the presence of cold air produced the maximum hardness in any of the aluminum alloys (2024, 6061, and 7075) that were examined. Aluminum 7075 has the lowest corrosion resistance, while aluminum 6061 has the strongest corrosion resistance when various testing conditions are taken into account.

Одной из самых серьезных проблем, с которой сталкиваются инженеры в различных отраслях промышленности, является коррозия. В настоящее время основное внимание уделяется коррозионным свойствам различных типов алюминиевых сплавов, широко используемых в промышленности. В связи с этим были протестированы алюминиевые сплавы Al 2024, Al 6061 и Al 7075. Кроме того, было исследовано влияние температуры окружающей среды на скорость коррозии каждой группы материалов. В качестве индикаторов коррозии образцов были измерены три статистических параметра, включая общую площадь коррозии, скорость коррозии (отношение общей площади коррозии к общей площади образца) и максимальный размер точки коррозии. Кроме того, с помощью метода Бринелля была измерена и представлена поверхностная твердость образцов. Наконец, был представлен алюминиевый сплав, наиболее устойчивый к коррозии при различных температурных режимах. Испытание на коррозию, проведенное в присутствии холодного воздуха, показало максимальную твердость среди всех исследованных алюминиевых сплавов (2024, 6061 и 7075). Алюминий 7075 имеет самую низкую коррозионную стойкость, тогда как алюминий 6061 имеет самую высокую коррозионную стойкость, если принять во внимание различные условия испытаний.
