Corrosion Embrittlement of Duralumin IV: The Use of Protective Coatings

Description: Although the corrosion resistance of sheet duralumin can be greatly improved by suitable heat treatment, protection of the surface is still necessary if long life under varied service conditions is to be insured. The coatings used for this purpose may be grouped into three classes: the varnish type of coating, the oxide type produced by a chemical treatment of the surface, and metallic coatings, of which aluminum appears to be the most promising. Since the necessary weather exposure tests are n… more

Study of Chromium-Frit-Type Coatings for High-Temperature Protection of Molybdenum

Description: "The achievement of more compact and efficient power plants for aircraft is dependent, among other factors, on the perfection of heat-resisting materials that are superior to those in current use. Molybdenum is one of the high-melting metals (melting point, 4750 F). It is fairly abundant and also can be worked into many of the shapes required in modern power plants. To permit its widespread use at elevated temperatures, however, some means must first be found to prevent its rapid oxidation" (p.… more

The Galvanic Corrosion Theory for Adherence of Porcelain-Enamel Ground Coats to Steel

Description: Note presenting an investigation of the galvanic corrosion theory of adherence between ground-coat porcelain enamels and steel as part of a broad study of the bonding mechanism between ceramics and metals. The theory is based on the mechanical anchoring of the enamel into the pits formed by the galvanic attack of the enamel on the steel surface.

Experimental Investigation of Air-Cooled Turbine Blades in Turbojet Engine 13: Endurance Evaluation of Several Protective Coatings Applied to Turbine Blades of Nonstrategic Steels

Description: Memorandum presenting an investigation of the durabilities of several protective coatings applied to air-cooled gas turbine rotor blades of nonstrategic steels in modified turbojet engines. Four types of coatings (ceramic, nickel, Nicrobraz, and aluminized) were applied to a total of 20 blades.

Effect of Oxygen Content of Furnace Atmosphere on Adherence of Vitreous Coatings to Iron

Description: Note presenting a series of vitreous coatings of the same basic composition, but with cobalt-oxide contents varying from 0 to 6.4 percent by weight, which was fired on ingot iron in atmospheres consisting of various oxygen-nitrogen mixtures. Results of the investigation showed that a decrease in the amount of oxygen in the firing atmosphere necessitated an increase in the amount of cobalt oxide in the enamel if optimum adherence was to be secured.

Preliminary report on development of coating for alloy case

Description: Coatings examined were selected industrial finishes reported to have good resistance to corrosion and included epoxy resins reinforced with fiberglass. For screening purposes,this preliminary work was done on commercial sheet Mg to which had been applied a dichromate finish. The coatings were tested for impact resistance, corrosion resistance, abrasion resistance, and thermal shock resistance. Conclusions for further work are outlined.

Fuel Element Development Program for the Pebble Bed Reactor

Description: Previous results from the Pebble Bed Reactor Fuel Element Development Program had shown the excellent promise of vapor-deposited Al2O3 doq5intw on UO2 particles as a low permeability high temperature fission product barrier. However, since the matrix material for the PBR fuel element is a graphite sphere, carbonaceous coatings on the dispersed fuel particles might be of more interest because of improved particle coating-matrix compatibility and no displacement of neutron moderating materials. … more

Effect of S8DR chromium diffusion treatment on the creep rupture properties of processed Hastelloy-N tubing

Description: Process development personnel have been seeking means of improving the (after thermal exposure) adhesion of the S8DR ceramic coating to chromized Hastelloy N tubing. This effort has led to the incorporation of an elevated temperature chromium diffusion treatment prior to the application of the ceramic coating. This report describes the results of tests performed to ascertain the influence of the additional thermal treatment on the 1400/sup 0/F creep-rupture properties of S8DR tubing.

Chemical vapor deposition of ZrC in small bore carbon-composite tubes

Description: Process conditions are described for the chemical vapor deposition of ZrC from ZrCl/sub 4/--CH/sub 4/--HCl--H/sub 2/--Ar vapor over the temperature range 1320 to 1775 deg K. From an analysis of the process conditions (initial composition of coating gas, axial temperature profile along the tubes, total pressure, and length of deposition time), the subsequent ZrC coat thickness profiles and thermodynamic data, an equation expressing the variation of the axial rate of ZrC deposition is derived.
