Choice and measurement of crucial aircraft coatings system properties

All components of an aerospace coatings system must be functioning properly for it to provide all of the elements of physical protection and optical performance that it was designed to provide. To insure proper coatings system functions over its desired lifetime, one must have the capability to define, measure and evaluate those system properties that determine these functions in use. For military aircraft, the desired properties can be summarized as mechanical/chemical protection of the airframe with controlled electromagnetic emission and reflection properties. This is easily enough said, but difficult to achieve in practice. There are many possible properties one can measure on an aerospace coatings system and the cohort of designers and users of these systems are uncertain of which is the absolute correct set of measurements to choose. They seek the set that gives the maximum amount of pertinent information at the least amount of effort and expense. The sine qua non of such properties has yet to be determined, but the current “best practice” thinking among the coatings science community focuses on system flexibility, adhesion, solvent resistance, corrosion protection and camouflage optics as determined over the coatings lifetime while taking into account the effects of UV exposure, hot and cold organic fluids, sea water, humidity and temperature cycling, mechanical stressing and abrasion. All of these must be considered in choosing the tests/results protocol that the coatings/pretreatment must undergo to be “fit for use.” We will discuss the current thinking on the measurements/exposures for aerospace coatings as well as the accuracy/validity that they provide in practice. We will concentrate on spectral, optical and electrochemical testing of coatings system properties and their changes in simulated and field exposure. The differences between test performance and real use performance will be considered, especially with respect to film application uniformity and film damage.     

Recent advances in aqueous two-component systems for heavy-duty metal protection

Although waterborne coatings have successfully replaced their solventborne counterparts in a variety of areas, their use generally has been limited to applications with relatively modest performance requirements. Recently, advances in technology have allowed for the design of waterborne coatings with performance suitable for more demanding applications. The emergence of two-component waterborne polyurethane coatings exemplifies this trend. These coatings can provide performance similar to that of solventborne 2-pack urethanes, but with much lower VOC. The chemistry of these coatings is discussed, in light of its relevance to some of the technical challenges, e.g., pot life and CO₂-gassing in thick films, unique to these systems. The use of 2-pack waterborne urethane topcoats in combination with low VOC waterborne acrylic/epoxy primers and intermediate coats is also described. Such multiple coat systems offer the promise of long term corrosion protection in severe industrial and marine environments, coupled with very low VOC.     

Self-healing epoxy coatings loaded with inhibitor-containing polyelectrolyte nanocapsules

The self-healing polymer coatings containing organic corrosion inhibitors are intensively investigated as an alternative for highly toxic Cr(VI)-based systems. Protective self-healing coatings are realized by embedding “smart” containers, able to release a corrosion inhibitor under some specific conditions occurring when the corrosion process starts (e.g. on pH change) or upon a mechanical damage. In this study a system with the corrosion inhibitors (2-methylbenzothiazole (BT) and 2-mercaptobenzothiazole (MBT)) encapsulated inside the polyelectrolyte nanocapsules embedded in the water-based epoxy coatings is tested for its self-healing performance. The nanocontainers were prepared by the electrostatic adsorption of polyelectrolytes directly on the oil phase drops containing the inhibiting agent. The results for BT emulsion droplets and the mixture of BT and MBT encapsulated by docusate sodium salt/poly(diallyldimethylammonium chloride) (AOT/PDADMAC) and docusate sodium salt/poly(diallyldimethylammonium chloride)/poly(styrene sulfonate) (AOT/PDADMAC/PSS) surface complexes are presented.The X-ray Photoelectron Spectroscopy (XPS) was used to confirm the release of the inhibitor from the scratched coating. The influence of the nanocapsules on the barrier properties and self-healing performance of the epoxy coatings were tested by electrochemical impedance spectroscopy (EIS) in NaCl solution, the salt spray test (SST) according to ISO9227 and filiform corrosion test (FFT) according to EN ISO 3665. Potential blistering was rated according to EN ISO 4628-2.

Hexafluorozirconic acid based surface pretreatments: Characterization and performance assessment

A new phosphate-free pretreatment from Henkel Corp. named TecTalis^®, was investigated. The treatment bath is composed of dilute hexafluorozirconic acid with small quantities of non-hazardous components containing Si and Cu. The corrosion resistance of treated steel was compared to samples treated in a phosphate conversion coating bath, in simple hexafluorozirconic acid and in TecTalis without the addition of the Cu-containing component. Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM) were used to characterize the coating surface morphology, structure and composition. A Quartz Crystal Microbalance (QCM) was used for studying film growth kinetics on thin films of pure Fe, Al and Zn. Electrochemical Impedance Spectroscopy (EIS) was performed on treated and painted steel for studying long-term corrosion performance of the coatings. The phosphate-free coating provided long-term corrosion performance comparable to that of phosphate conversion coatings. The coatings uniformly cover the surface in the form of 10–20 nm sized nodules and clusters of these features up to 500 nm in size. The coatings are usually about 20–30 nm thick and are mostly composed of Zr and O with enrichment of copper at randomly distributed locations and clusters.
