AIRCRAFT WHEEL PART HAVING IMPROVED CORROSION RESISTANCE
A hardened and tempered steel member of high tensile strength and wear and corrosion resistance, is produced thermal spraying of a selected portion with a tungsten carbide-cobalt composition, consisting of 78-90% tungsten carbide, 10-19% cobalt, and a sacrificial ceramic-metallic coating to provide corrosion resistance.

METHOD FOR APPLYING HOT-GAS ANTICORROSIVE COATINGS
Hot-gas anticorrosive coatings are applied to high-temperature nickel- or cobalt-based alloys, in the form of a gradient layer containing a platinum group metal combined with aluminum. The components are introduced in a directed high-temperature high-enthalpy free jet from solid, liquid or gaseous precursors in specific mixture ratios.

METHOD FOR REMOVING A LAYER
Corroded structural components are often reused, therefore the corrosion product has to be removed. Conventional methods for doing so are time-consuming so the corrosion product is pretreated by exposing it to salt so that the corrosion product can be removed more rapidly. Sodium sulfate (NA2SO4) and/or cobalt sulfate (CoSO4) are used for the salt exposure.

LIQUID TRIVALENT CHROMATE FOR ALUMINUM OR ALUMINUM ALLOY AND METHOD FOR FORMING CORROSION-RESISTANT FILM OVER SURFACE OF ALUMINUM OR ALUMINUM ALLOY BY USING SAME
A film with excellent corrosion resistance and adhesion to coating compositions on the surface of aluminum or an aluminum alloy uses a liquid trivalent chromate containing no harmful hexavalent chromium. The concentration of zinc, cobalt, nickel or combination thereof is within the range of 0.01-100 g/L and the concentration of fluorine is within the range of 0.01-50 g/L.

ANTICORROSIVE, CERAMIC MATERIAL FOR EVAPORATING METALS, ESPECIALLY ALUMINUM, METHOD FOR THE PRODUCTION OF SUCH MATERIAL AND EVAPORATOR MADE OF SUCH A MATERIAL
An anticorrosive ceramic material especially for evaporating metals, such as aluminium, contains 20-38 wt.% of titanium, 23.6-41 wt.% of boron predominantly in the form of titanium diboride. To increase the corrosion resistance of such a material, it contains iron, cobalt, niobium, molybdenum, hafnium, vanadium or tantalum preferably in the form of borides.
