ZIRCONIUM PRETREATMENT COMPOSITIONS CONTAINING MOLYBDENUM, ASSOCIATED METHODS FOR TREATING METAL SUBSTRATES, AND RELATED COATED METAL SUBSTRATES Russian patent published in 2017 - IPC C23C22/44 C23C22/83 C25D13/20 

Abstract RU 2611610 C2

FIELD: metal processing.

SUBSTANCE: invention relates to treatment of metal substrates, such as cold-rolled steel, electrogalvanised steel or aluminium alloys. Pretreatment composition for treatment of metal substrate before application of coating comprises a Group IIIB and/or IVB Group metal, free fluoride, molybdenum and lithium, in which on molybdenum is in amount of 2 to 500 parts per million in terms of total weight of ingredients of pretreatment composition, wherein pretreatment composition in contact with substrate reacts with surface of substrate, chemically changes surface of substrate and binds to it with formation of a protective layer. Method of applying coating on a metal substrate includes pretreatment of metal substrate with pretreatment composition and electrophoretic deposition of a coating composition on metal substrate, wherein said coating composition contains yttrium.

EFFECT: invention ensures production of corrosion-resistant coatings without use of phosphate- and/or chromate-containing compositions.
