摘要： A conversion coating, predominantly consisting of tin phosphate, can be deposited on steel or tin plated steel surfaces by contact with a solution containing phosphate ions, tin ions, an oxidizing agent such as chlorate, and a chelating agent for the tin ions, the latter to prevent the rapid loss of tin from the solution that otherwise would occur. A coating that confers excellent resistance to corrosion in hot water is formed on drawn and ironed thinly tin plated cans.

摘要： A method of producing titanium and titanium alloys having improved lubricity and cold working characteristics includes immersing titanium or titanium alloy as the cathode in an electrolytic conversion coating bath containing acidified zinc phosphate and forming a zinc phosphate coating on the titanium or titanium alloy by maintaining electrolysis conditions in the bath. Further improvements are achieved by pretreatment of the titanium or titanium alloy with a surface adjustment agent prior to immersion in the electrolytic conversion coating bath. The products are further treated with conventional lubricants and exhibit improved working characteristics.

摘要： This invention concerns a humidity sensor wherein a chemical conversion coating, giving attention to the property that it undergoes an impedance decrease with adsorption of moisture, is used as humidity sensing element which is characterizied by an extremely short electrode distance, greatly improved sensitivity, high speed response, stable performance over a long period of time, high reliability and cheaper production cost.The principal point that characterizes the humidity sensor in this invention is that the chemical conversion coating deposited on the metal surface with or without an electrolysis application, is made usable as a humidity sensing element. For the chemical conversion coating, such coatings as phosphate, oxalate, titanium fluoro-complex, chromium phosphate and non-chromium types are used.On top of this chemical conversion coating, application of a humidity sensing film is effected to further improve humidity sensing performance.

摘要： A conversion coating solution for treating metallic surfaces is able to form conversion coating films having excellent anticorrosiveness and giving good adhesiveness and gloss to the overcoating. The conversion coating solution has a pH value of 5.5 to 6.5 and contains 0.1 to 50 g/liter as phosphate ion of acid salts of alkali phosphates, 0.01 to 0.5 g/liter of stannous ion and 2 to 12-fold by weight as much fluorine ion as the stannous ion. The conversion coating solution may be further combined with 0.2 to 5 g/liter of at least one of pyrazole compounds, hydroxylamine compounds and hydrazine compounds.

摘要： Disclosed is a process for treating aluminum wherein the surface is contacted with a solution containing phosphate, a tannin, titanium and fluoride prior to inking or lacquering. The process produces a coating exhibiting adhesion, color and corrosion resistance comparable to that obtained via conventional chromium-based processes without creating the pollution problems of chromium disposal.
