Abstract: Chromium electrodeposits improve the hardness, wear resistance, and corrosion resistance of engineering components. These properties made chromium very acceptable for electroplating. Aluminum alloy AA6060 is used for enclosing constructions such as windows, facade construction, winter gardens, internal partitions, stairs, fences, rail, heating and cooling pipes, furniture, etc. These applications make this alloy extremely interesting for electroplating technology. This paper studies mass of electrodeposited chromium and its thickness in different five samples of aluminum alloy AA6060 which have undergone the galvanizing process. The galvanizing process is performed for different time intervals 20 min, 40 min, 60 min, 80 min and 100 min, respectively. Masses of the samples of aluminum alloy were measured before and after galvanizing with a technical scale. The thickness of electrodeposited chromium in different samples was defined from photographs obtained with metallurgical optical microscope with a magnification of 60500X. For the electrolysis process samples were prepared with abrasive papers while for optical microscope observation was used a polishing machine. The solution used for the electrolysis process was potassium dichromate. The methods used during work of this paper have been: electroplating, metallographic specimen preparation and optical microscopy. The key process of this work is galvanizing process while the main law in accordance with which galvanizing process takes place is Faraday’s first law of electrolysis.
