Coatings suitability

Although transformers suitable for other industrial installations are generally suitable for producing applications, certain options may be desirable— primarily due to environmental considerations. At locations subject to harsh environmental conditions, and particularly at locations subject to washdown with high-pressure hoses, non-ventilated enclosures are desirable, if not necessary. Likewise, at locations subjected to salt water and salt-laden air, it often is desirable to specify copper windings and lead wires. Most manufacturers provide standard units with aluminum windings and lead wires. Even if aluminum coils are used, it is almost always desirable to require stranded copper lead wires. This will lessen corrosion and loose terminal problems when transformers arc interconnected to the facility electrical system with copper conductors. If the transformers are to be installed outdoors in corrosive environments, cases should be of corrosion-resistant material (e.g., stainless steel) or be provided with an exterior coating suitable for the location. 

Flow coating Suitable for use on most articles. Gives good penetration into pores of castings Similar to dipping, but the defects not so marked. Tendency for greater solvent loss. 

Lidding substrates are required to be sealed to the preformed blister materials. An essential component of lidding material is a coating suitable for heat sealing. The heat sealing lacquers used must comply with FDA standards set forth in the Code of Federal Regulations (CFR) for indirect food additives. 

For trace analysis in fluids, some Raman sensors (try to) make use of the SERS effect to increase their sensitivity. While the basic sensor layout for SERS sensors is similar to non-enhanced Raman sensors, somehow the metal particles have to be added. Other than in the laboratory, where the necessary metal particles can be added as colloidal solution to the sample, for sensor applications the particles must be suitably immobilised. In most cases, this is achieved by depositing the metal particles onto the surfaces of the excitation waveguide or the interface window and covering them with a suitable protection layer. The additional layer is required as otherwise washout effects or chemical reactions between e.g. sulphur-compounds and the particles reduce the enhancement effect. Alternatively, it is also possible to disperse the metal particles in the layer material before coating and apply them in one step with the coating. Suitable protection or matrix materials for SERS substrates could be e.g. sol-gel layers or polymer coatings. In either... 

In the field of metallic powder applications, a method of plasma spray coating suitable for biomedical materials has been developed using titanium and calcium phosphate composite powder. By means of the mechanical shock process, the appropriate composite powder was prepared, and plasma sprayed on Ti substrate under a low-pressure argon atmosphere. A porous Ti coating layer was obtained in which the surface and the inside of the pores were covered thinly with hydroxyapatite. This surface coating is expected to show excellent bone ingrowth and fixation with bone (21). 

Kosaraju et al., 2006), as well as to encapsulate probiotic cultures (Fei-joo et al., 1997) and to make vitamin E nanoparticles (100 nm) stabilized by a starch coating suitable for fortified beverages (Chen and Wagner, 2004). And, by using microfluidization followed by solvent evaporation, Tan and Nakajima (2005) have reported preparation of (3-carotene nanodispersions (60-140 nm). 

The Air Force is interested in the development of a fire-retardant coating suitable for aircraft use. The problem of fire control is ever present on aircraft, which are essentially flying power plants surrounded by tanks of highly flammable fuel, and carrying personnel and cargo. 

Once the initial conductive metallic film has been prepared as described virtually any coating suitable for electrodeposition can be applied to it. In practice the most usual system is nickel-chromium ( chrome plating ), which— provided application is as it should be—gives excellent resistance to abrasion, to corrosion, and generally is very durable. For certain types of work, coatings of precious metal (especially gold) are popular.

Different methods used to prepare titanium diboride have been reviewed by Samsonov et al. (1975). At present, it is mainly produced as a powder by thermochemical reduction of boron and titanium oxides followed by hot pressing and sintering to process the final product. The less costly alternative appears to be to coat suitable substrate materials with TiB2 or TiB2-based composites by hot pressing, plasma spraying, chemical vapor deposition, etc. 

The length of the tubes can range up to many micrometers and depends on the reaction time. The diameter of the MWNT can be controlled as well by coating suitably sized catalyst particles onto the substrate. Generally, the samples obtained are soiled with other structures, mainly with graphite-coated catalyst particles and so-called carbon nanoparticles (refer to Chapter 4).

To provide electronic coupling between the incorporated CoP(pyH)44+ counterions and the graphite electrode surface it was necessary to add to the coatings suitable redox mediators wiUi much larger diffusion coefficients. In Figive IB is shown the cyclic voltammetric response obtained from a Nafion coating which contained Os(bpy)32+ (bpy = 2,2-bipyridine) and Ru(NH3)e3+ as well as CoP(pyH)44+. The pair of current peaks near —0.25 V arises fix)m the Ru(NH3)63+/2+ couple and the pair near 0.6 V from the Os(bpy)33+/2+ coimle. This pair of mediators was chosen because they both have reasonable diflusional rates in Nafion and their formal potentials lie on either side of the formal potential of the CoP(pyH)4 couple (—O.IV) so that the cobalt center of the porphyrin could be repetitively cycled between its oxidized and reduced states by me mediator counterions which diffused to and from the electrode surface where they were oxidized or reduced.
