This specification covers a barrier coating in the form of a ready-to-be applied liquid with a consistency suitable for brush, spray, or dip application to exterior surfaces of aircraft.
This specification establishes requirements for a temporary protective coating (TPC) intended to protect aluminum surfaces from damage and corrosion. This specification also establishes requirements for an alkaline remover used to strip the specified TPCs.
This specification covers a corrosion and heat resistant aluminum coating material supplied as a liquid of suitable consistency for coating parts after being thoroughly mixed.
This specification covers the engineering requirements for producing an anodic coating on aluminum and aluminum alloys which are subsequently sealed with an organic resin.
In a car body painting system, the contribution ratio of phosphate treatment as the paint base coating reaches about 20% in corrosion resistance according to the analysis of variance of experimental results. ...With the zinc phosphate type conversion treatment, coating mainly consisting of hopeite and phosphophyllite is formed on the surface of steel sheet. ...With an electrodeposition paint base, corrosion resistance becomes higher as the content of phosphophyllite in the coating becomes higher. The reason for this may be sought in the dissolution of phosphate coating when ED paint is applied (solubility) and when it is decomposed during subsequent baking (heat resistance).
These additional tests can provide informational data for characterizing the coatings and may be useful to operators when evaluating the coatings....This SAE Aerospace Information Report (AIR) provides descriptions of test methods for determining if an aircraft surface coating of any thickness has adverse effects on aircraft deicing/anti-icing fluids with respect to fluid holdover time performance and aerodynamic performance. ...Although not the primary mandate of the G-12 Aircraft Ground Deicing Committee, this document also provides descriptions of suggested test methods for evaluating aircraft surface coatings with respect to durability, hardness, weathering, aerodynamic drag, ice adhesion, ice accumulation, contact angle, and thermal conductivity.
Along those lines, General Motors do Brasil started to develop a protective coating that is corrosion resistant and environment friendly. At first, this will be used for fasteners. ...This study describes metallic and organometallic coatings with an increased resistance to corrosion associated to temperature, free of such harmful metals as cadmium, nickel, lead, chromium, etc. ...The friction coefficient is also related to the performance (efficiency) of the screw joint. The coating is completely recyclable, special consideration being given to reduced energy consumption, reduced metal waste and simplified waste handling during coating application to control proliferation and usage of toxic substances.
