.... The chemical reactions deposit the desired element (aluminum in this case) on the surface of metallic alloys. The coating element subsequently diffuses into the substrate to modify the surface of the underlying alloy. Under oxidizing conditions, the surface modified alloy forms a passive oxide layer...

... is the deposition of aluminum onto high strength steel substrates the ion vapor deposition (IVD) process. While this process is effective in mitigating corrosion, the facilities required to perform this task are highly specialized, and the deposition process is line-of-sight only. To address these shortfalls, we...

... reactions. Enriching the surface of metallic alloys with aluminum, chromium or silicon can result in the formation of an oxide scale to protect the base alloy from corrosive environments in service. 2 In this study, the nature and ease of formation of the aluminide layer as a function of the aluminizing...

... ABSTRACT Aluminum molds are frequently used in the plastics manufacturing industry. Relative to steels, aluminum alloys offer such benefits as lower weight, improved machining and polishing, and reduced cycle time due to aluminum’s significantly higher thermal conductivity. However, corrosion...

... ABSTRACT Corrosion of aluminum and aluminum alloys under atmospheric exposure has been well documented for outdoor conditions. While these studies expose the effects of environmental severity they do not explicitly establish the dependence of corrosion rate on salt loading. Accelerated...

Abstract Non-ferrous metals and alloys such as aluminum, copper, and brass are frequently used for a wide range of applications in several industries, including the automotive and electronics industries. Under ambient conditions, these metals are protected from corrosion by passivating oxide...
