Metals engineering surfaces

Additive interactions take place in lubricating oil formulation and at surfaces (Kajdas, 2001 Spikes, 1989). At surfaces, additive interactions should protect metallic engine surfaces from corrosion, prevent rusting, build-up of varnishes, agglomeration of particles, and form low friction and protective films. In the base... 

Corrosion Inhibitor - helps prevent rusting of metal engine components. Also, corrosion inhibitors provide a protective film on metal surfaces to aid in improving the lubricating properties of jet fuel. Use is not permitted in aviation gasoline and civil jet fuels, but is mandatory in military jet fuel grades. 

Acrylics, unsaturated polyesters and other monomer-based adhesives containing ethy-lenic unsaturation, cure by formation of free peroxide radicals formed with transition metal ion donators such as cobalt, iron, copper and nickel. In engineering applications the presence of transition metals on surfaces sees them act as initiators by forming the free peroxide radicals from the added peroxide compound(s). The base monomers usually contain inhibitors such as phenols or other materials classed as peroxide stabilisers to...

The importance of a clean surface for painting is paramount (see Engineering surfaces of metals). For metallic substrates, either mechanical or chemical surface treatment is almost always needed to remove surface contamination and promote adhesion. Chemical pre-treatment of metals prior to painting is an effective method of surface conversion that can provide both corrosion resistance and improved paint adhesion. For ferrous metals, the most common chemical pre-treatment is a phosphate for aluminium (and many other non-ferrous metals), the most effective pre-treatment is chromate. Metals must first be cleaned with an alkaline cleaner and then rinsed before they can be converted chemically in an immersion bath or by spray.

An engineered glucose oxidase made by the incorporation of ferrocene derivatives into the enzyme has a similar effect [134]. A covalent coupling of ferrocene carboxylic acids to the enzyme (12 ferrocene moieties attached [135]) enables direct tunneling of electrons through the protein from ferrocene to ferrocene and hence to a clean metal electrode surface.

It is necessary to get much information from other disciplines, especially organic metallic chemistry, surface sciences, solid-state chemistry, material sciences, biochemistry and bionic chemistry, chemical reaction engineering, chemical kinetics and dynamicology s because of the complexity of catalyst and cataljdic phenomena.
