Corrosion Protection of Selected Aluminum Wrought Alloys applied in the Automotive Industry

Abstract

The paper aims to review the corrosion properties of selected aluminum alloys applied in the automotive industry which are used in heat exchangers, bodyworks and car wires. Particular attention was focused on application of selected chemical compounds which added to corrosive environment in certain amounts lead to decrease of corrosion rate of protected aluminium alloy. Considered different environmental conditions which are simulating real vehicle exploitation. At review analyzed ability to application mentioned compounds on automotive parts, because there is needed fill of following requirements: environmentally friendly, relatively inexpensive and characterized by long-term performance under certain conditions. Main conclusion of review is that there are needed extension of research regarding to application of inhibitive compounds especially on the surface of cars wires.
