Lubrication corrosion

Metalworking fluids contain mineral oils (refer to p. 80) or synthetic lubricants they are used neat or in admixture with water. They may contain small amounts of biocides, stabilizers, emulsifiers, coiTosion inhibitors, fragrances and extreme pressure additives. The formulations render them suitable for application to metal being worked, generally from a recirculatory system, to provide lubrication, corrosion protection, swarf removal and cooling of the tool and machined surface.

These are true chemical solutions and are mixtures of soluble polyglycols (to give lubricity), corrosion inhibitors and water soluble extreme pressure additives. They are subject to attack by micro-organisms and as a consequence, they are often formulated with one or more preservatives.

The field of materials science has grown dramatically in the past decade, with new materials being synthesized and/or developed for applications such as lubrication, corrosion protection, electronics, paints and coatings, and chemical separations. Many of these materials have complex properties quite different from those associated with simple ideal substances. Since the chemical and physical properties of a material determine its ability to meet the often stringent specifications required for a given application, characterizing the properties of materials plays a vital role in materials science. 

Amphoteric surfactants offer an excellent degree of lubrication, corrosion inhibitor, and wetting action and provide a protective colloid for silk and wool processing. The major uses of amphoterics are in the scouring and dyeing of protein fibres to prevent chafing, crack marks and crow s feet. Amphoterics are comparatively expensive and some of them are not heat stable and hence cannot be used at elevated temperature. 

In an attempt to lower their surface energy, solids almost always will adsorb small molecules, such as H2O or O2, on their surfaces. Molecules which form molecular solids have much smaller surface tensions than other solids. The study of surfaces is a difficult one, it can be seen. Fortunately a number of very special experimental methods have been developed, and surfaces may be studied in great detail. Such studies are useful in many important practical areas, such as adhesion, lubrication, corrosion and adsorption. However, the most important area is probably heterogeneous catalysis.

The technique of choice for studying thin films on metals (or certain other substrates) directly is single reflection RAIR [47-54]. The limitation here is that the substrate must be very smooth, but this can be easily achieved by polishing the metal before deposition of the film. Characterizations of thin organic layers on metal (oxide) surfaces, such as occur in lubricants, corrosion inhibitors, adhesives, polymers, paints, and so forth, are specific applications of this rather recent form of FTIR. It should be noted that the relative band positions and shapes may be different in this technique than in conventional transmission IR. The spectrum may also change with the thickness of the organic film, which implies that polymer/metal interactions are in principle observed [47,51]. The teehnique is so surface sensitive that oxidation of metals can be determined in situ [51] and the packing...
