Coatings characteristics

TBCs consist of two different materials applied to the hot side of the component a bond coat applied to the surface of the part, and an insulating oxide applied over the bond coat. Characteristics of TBCs are that the insulation is porous, and they have two layers. The first layer is a bond coat of NICrAlY, and the second is a top coat of YTTRIA stabilized Zirconia.

Iridium has been deposited from chloride-sulphamate and from bromide electrolytes , but coating characteristics have not been fully evaluated. The bromide electrolytes were further developed by Tyrrell for the deposition of a range of binary and some ternary alloys of the platinum metals, but, other than the platinum-iridium system, no commercial exploitation of these processes has yet been made.

Figure 35.1 depicts the dependence of the deposition rate on the discharge parameter WjFM. The figure is essentially the same as Figure 8.3 and, if plotted using D.R./ FM, the same as Figure 8.4. Such a plot is necessary to identify the domain of LCVD, namely, the energy-deficient domain or monomer-deficient domain. Based on this figure, 2.6GJ/kg (energy-deficient domain) and 21.8GJ/kg (monomer-deficient domain) were selected for analysis of coating characteristics.

Plastic tubes are also employed. Here, the choice of the plastic is also critical. Polypropylene is preferred over polystyrene, since it is easier to handle and is less breakable. It is mostly used in commercial kits. There is, however, little or no difference in the coating characteristics of the two plastics. The size of the tubes is 10-12x70-75 mm, and their form may be conical, round- or flat-bottom. Tubes generally require larger volumes (1 ml) than microtitre plates, but their surface/volume ratio can be increased by rotating almost horizontally in circular test-tube racks. Upon slow rotation, a relatively large surface is covered. Disposable polystyrene... 

The Intercide OBF microbiocides are based on the active ingredient 2-n-octyl-4-isothiazolin-3-one (OIT). The products are effective fungicides which are widely used in paints and coatings. Characteristics and applications are described for Intercide grades OBF-8-DINP, and OBF-8-ED6. OIT is highly compatible with PVC and offers advantages over OBPA in terms of resistance to UV radiation. 

The vinyl latex systems are similar to the solvent vinyl systems with respect to coating characteristics that is, they both have low coating viscosity. Removal of at least 50% of the coating weight as water requires ovens with minimum available temperatures of 212 °F. Since organic solvents are not present, fire hazards are diminished. The high emulsifier levels in these systems will limit their applications where water contact or sensitivity are important... 

The exterior surfaces of the air-atomized sulfur coatings characteristically have an uneven, pebbly texture of the type shown in Figure 2. The uneven texture results from the impact and the flow characteristics of the sulfur droplets that accrete to form the coating as the urea particles...
