[1] Wrocław University of Technology, Faculty of Chemistry, Department of Chemical Engineering, Wrocław, Poland

Nitrogen oxides are one of the more dangerous ingredients contaminating the atmosphere. They are considered to be almost ten times more harmful than carbon monoxide, and sulfur dioxide several times. A whole range of photochemical reactions involving nitrogen oxides are responsible for ... Read More

Effect of Pretreatments on Throwing Power of Sacrificial Metallic Coatings

J. S. Lee [1],
[1] Naval Research Laboratory, Stennis Space Center, MS, USA

Sacrificial metallic coatings (e.g. Mg-Rich Primer [MgRP]) have been evaluated for protection of aircraft aluminum alloy AA2024-T351 in marine immersion and atmospheric conditions. MgRP is designed to create a galvanic couple between the Al substratum and the Mg pigment in the primer. ... Read More
