摘要： Heating an aqueous mixture of a fluoroacid such as H2TiF6 and an oxide, hydroxide, and/or carbonate such as silica produces a clear mixture with long term stability against settling of any solid phase, even when the oxide, hydroxide, or carbonate phase before heating was a dispersed solid with sufficiently large particles to scatter light and make the mixture before heating cloudy. The clear mixture produced by heating can either be mixed with water soluble and/or water dispersible polymers, for example with dispersed polymers of the diglycidyl ether of bisphenol-A or an acrylic acid polymer, or with soluble hexavalent and/or trivalent chromium, to produce a composition that improves the corrosion resistance of metals treated with the composition, especially after subsequent painting. Another composition that improves the corrosion resistance of metals after contact with them is an aqueous solution of a mixture of: (A') a water soluble or dispersible polymer having at least one -OH group per polymer molecule selected from the group consisting of polyvinyl alcohol, polyethylene glycol, modified starch, and mixtures thereof, and (B') polymers and copolymers of acrylic and methacrylic acid and their salts.

摘要： There is provided a magnesium alloy member having mechanical properties and corrosion resistance and a method of manufacturing the magnesium alloy member. A magnesium alloy member has a base material made of a magnesium alloy, and an anticorrosive film formed on the base material. The base material is a rolled magnesium alloy including 5 to 11% by mass of Al. By using a base material including a large amount of Al, a magnesium alloy member having excellent mechanical properties and high corrosion resistance can be produced. In addition, by using a rolled material, the number of surface defects at the time of casting is small, and the frequency of compensation processes such as undercoating and puttying can be reduced:

摘要： A previously heat treated aluminum alloy rivet is sand blasted with aluminum oxide, washed with a corrosion resistant solution, dried, and then a coating is applied to the rivet. The coating includes solvent, resin, plasticizer and a corrosion inhibitor. The coating is cured at an elevated temperature below 300°F, preferably in the order of 250°F for about an hour, or between one-half and one and one-half hours. The resultant rivet has a relative thick gasket-like coating about 0.0007 to about 0.001 or 0.002 inch thick, and retains its high shear strength resulting from the initial pre-coating heat treatment. As an alternative pre-treatment, the rivets may be chromic acid anodized.
