摘要： The insulating film comprised mainly of phosphate or chromate is improved in its insulation property required for the laminated core e.g., a transformer, the blanking property required for manufacturing the core sections from the electrical steel sheet, and the lamination weldability. The organic resin particles used for controlling the surface roughness of the film are preliminarily treated with a dispersion improver, and then added to the emulsion resin, which is then mixed with the phosphate or chromate.

摘要： An improved method of chromizing the surface of a ferritic boiler component. An aqueous coating composition is applied to the surface to be chromized, which includes at least 10% by weight of chromium, at least 12% by weight alumina, a binder of ammonium alginate or methyl cellulose, and a halide activator, and in which the weight ratio of chromium to water is greater than 0.7. Alternative embodiments involve the application of a halide activator over the top of a previously applied and dried coating that is lacking said halide activator, as well as to the application of multiple layer single component slurry coatings.

摘要： An automobile fuel container material and container has good workability, corrosion resistance of internal and external surfaces and weldability. Excellent environmental adaptability arises from the material being free from the elution of harmful components such as lead and chromium(VI). The automobile fuel container material includes a steel sheet, 5 to 80 g/m2 zinc plating as a first layer on at least one side of the surface of the steel sheet, 10 g/m2 nickel plating as a second layer, and not more than 5 g/m2 of a post-treatment layer. The post-treatment layer forms by coating partially reduced chromic acid and a reducing organic compound or can be an electrolytic chromate film as a lower layer and a resin as an upper layer.
