摘要： To extend the temperature range of composite materials the composite material is made up of more than two hard layers which are joined with thin intermediate layers of viscoelastic material where one intermediate layer differs from another intermediate layer in that its softening range lies in a different temperature range so that the damping ranges of the intermediate layers also are different.

摘要： A process for phosphating zinc-plated metal articles, particularly electrolytically zinc-plated steel sheets, by treatment thereof for a short period with an acidic phosphating solution which, in addition to zinc and phosphate ions, can contain other metal cations and/or anions of oxygen-containing acids having an accelerating effect, wherein the phosphating solution has a content of Zn.sup.2+ -cations of between about 1 and 2.5 g/l, a free acid content in the range from 0.8 to 3 points, and the acid ratio of total acid to free acid in the range from 5 to 10. The phosphating treatment is carried out for a period of time not in excess of about 5 seconds.
