摘要： Very good masking of pack diffusion aluminizing or chromizing on any metal to keep portions from being diffusion coated, is effected by localized coating the lowest layer of which is depletion-reducing masking powder the metal portion of which can have same composition as substrates, mixed with inert refractory diluent and non-contaminating film-former such as acrylic resin. The upper coating layer can be of non-contaminating particles like nickel or Cr.sub.2 O.sub.3 that upon aluminizing or chromizing become coherently held together to form a secure sheath. Such sheath can also be used for holding localized diffusion-coating layer in place. Film-former can be dissolved in volatile solvent, preferably methyl chloroform, in which masking powder or sheath-forming powder is suspended. Chromizing can be performed before aluminizing for greater effects. Aluminizing of metals like iron and nickel followed by leaching out much of the diffused-in aluminum, gives these substrates a pyrophoric and catalytic surface. Foil, wire or powder can be thus activated, and very fine activated powder when discharged into the air forms warm cloud that settles very slowly and decoys heat-seeking missiles.

摘要： Heating or heat generation in general can be from activated aluminides of molybdenum, zirconium or other similar ignitible metals. Activation is by leaching out some of the aluminum and leaves a product which is highly pyrotechnic but not pyrophoric. Activation of such alloy renders activated surface porous so it car receive impregnants such as lubricants to thus act as a bearing. Pyrotechnic webs for use as decoys against heat-seeking missiles can be folded so that portions interfere with the free radiation of other portions, to thus extend the time the webs remain at high temperature. The folding also improves the trajectory through which the webs fall when discharged into the air. The web can be coated with a thin layer of powdered silica, alumina or zirconia to increase the proportion of its radiation in the 8 to 14 micron range.

摘要： Low temperature aluminum diffusion is of better quality when effected with a pack energized by aluminum chloride or other material that does not generate nitrogen and is shielded from contacting the work pieces until after the pack is heated to energizing temperatures. The resulting aluminizing very effectively protects steels against corrosion in marine atmospheres, particularly when there is a chromate-type coating applied over the aluminizing. Highly effective chromate-type coating mixture consists essentially of aqueous solution of chromic and phosphoric acid also containing magnesium salts of said acids with or without dispersed polytetrafluoroethylene particles. The salts of divalent metals such as calcium, zinc, strontium, manganese, cobalt and nickel whose chromates are soluble in acid, can be used instead of or in addition to the magnesium. Such coating mixture is best applied over porous pre-coating of colloidal inert particles.

摘要： RICH CHROMIUM DIFFUSION COATING ON TD NICKEL OR TD NICHROME IS OBTAINED IN ONE STEP BY EMBEDDING WORK IN CHROMIUM DIFFUSION COATING PACK CONTAINING NICKEL WITH OR WITHOUT SOME COBALT, AND HELD IN UNSEALED RETORT CUP AT LEAST 15 INCHES HIGH. MAGNESIUM HALIDE IS HELPFUL TO HAVE IN THE PACK AND PACK CAN ALSO CONTAIN METALLIC IRON TO REDUCE COATING TEMPERATURE. MASKING IS ARRANGED BY COVERING THE SITES TO BE MASKED WITH A LAYER OF A MIXTURE OF NICKEL POWDER AND INERT FILLER. FOR BETTER HIGH TEMPERATURE OXIDATION RESISTANCE THE CHROMIUM-RUCH COATING IS COVERED BY AN ALUMINUM DIFFUSION COATING FROM A SIMPLE ALUMINUM DIFFUSION PACK OR ONE THAT HAS THE ALUMINUM MIXED WITH CHROMIUM. LOW TEMPERATURE ALUMINUM DIFFUSION IS MORE UNIFORM WHEN PACK ENERGIZER IS ALUMINUM CHLORIDE OR OTHER MATERIAL THAT DOES NOT GENERATE NITROGEN. A MANGANESE-CONTAINING ALUMINIZING PACK GIVES BETTER PROTECTION THAN A SIMPLE ALUMINIZING PACK, PARTICULARLY AGAINST MARINE CORROSION, AND WHEN THERE IS A CONVERSION COATING APPLIED OVER THE ALUMINIZING. CONVERSION COATING MIXTURE WETS ALUMINIZED FERROUS SURFACE BETTER WHEN THE BLACK IS THEN REMOVED WITH THE HELP OF NITRIC ACID. ALUMINIZED SUPERALLOY CAN BE HEATED IN AIR TO WHITEN IT, THEN CLEANED TO GIVE PRODUCT HAVING MORE ADHERENT CASE. ALSO ADDING SOME LANTHANUM OR YTTRIUM TO SUPERALLOY LIKE WI 52 GIVES BETTER HIGH TEMPERATURE RESISTANCE.

摘要： A metal article such as a gas turbine component may include a super-diffusion coating with unusually high content of the desired constituent. The coating may be provided by combining two or more diffusion coating processes, each process interdiffusing the desired constituent with the metal article from a different metal source. The metal article can be placed in physical contact with a metal source in powder form as a first source, and the article can also be exposed an additional metal vapor source. Super-chromide coatings can be produced with alpha-chrome content in a manner that also provides the coating with sufficient ductility for long-term durability. For example, a shank portion of a gas turbine blade may be provided with a chromide coating with at least a portion of the coating having from 60-90% chromium content.
