Abstract: A chromium-free welding consumable and a method of welding stainless steel to reduce the presence of chromium emissions. The consumable is made from an alloy that reduces the emission of chromium during a welding process, and include predominantly nickel, with between approximately five and twenty five percent by weight copper, up to approximately five percent by weight of palladium, up to approximately ten percent by weight of molybdenum and up to five percent non-copper alloying ingredients. Welding consumables made from the alloy are particularly well-suited for welding austenitic stainless steels, such as type 304 stainless steel. The method involves using chromium-free weld filler material with a stainless steel base material.

Abstract: A chromium-free welding consumable and a method of welding stainless steel to reduce the presence of chromium emissions. The consumable is made from an alloy that reduces the emission of chromium during a welding process, and include predominantly nickel, with between approximately five and ten weight percent copper, up to approximately two percent by weight of ruthenium and up to five percent non-copper alloying ingredients. Welding consumables made from the alloy are particularly well-suited for welding austenitic stainless steels, such as type 304 stainless steel. The method involves using chromium-free weld filler material with a stainless steel base material.

Abstract: The corrosion sensing or detecting composition and method of the present invention preferably includes an aqueous gel that is adapted as a temporary coating for a surface of a material and that includes at least one composition that changes its appearance in response to corrosion occurring on the surface of the material. In a variation of the preferred embodiment, the at least one composition is further adapted to change color in response to a change in hydrogen ion concentration proximate to the surface of the material. The present invention is also directed to a vehicle, such as an aircraft, a spacecraft, an automotive vehicle, an amphibious vehicle, a boat, and a ship, that is prepared for corrosion inspection. The vehicle and method for inspecting the vehicle preferably include a painted material surface with the paint removed for application of a removable corrosion-detecting coating that changes its appearance in response to corrosion occurring on the surface.

Abstract: A corrosion protecting film layer is formed on a non-passivating non-noble metal, such as cobalt, by placing the metal in a dilute solution of Cu.sup.+2 ions and benzotriazole (1 H-BTA). Exposure of the metal to a solution containing Cu.sup.+2 and 1 H-BTA results in a spontaneous interaction of Cu.sup.+2 and the metal to produce a film layer of Cu(I) BTA on the metal surface to create a permanent corrosion protection for the metal. A borate buffer, such as boric acid and a borate, can be added to the solution to adjust the pH of the solution to be in the range between 8 and 9.

Abstract: The present invention relates to the improvement of corrosion wear resistance of iron-manganese (FeMn) film by ion implantation and subsequent annealing without substantially affecting the magnetic properties of the magnetic material. A highly corrosive and wear resistant FeMn film is disclosed comprised of a layer of FeMn and at least one protective layer selected from the group consisting of nitrides, carbides and oxides, with said protective layer being formed at the surface of the FeMn layer.
