GALVANIZING METHOD WITH ZINCATE BATH

摘要

PROBLEM TO BE SOLVED: To provide a galvanizing method with an alkaline zincate bath for reducing plating time by the improvement of a zinc dissolution method, an insoluble anode, a plating bath composition and a plating liquid brightener. SOLUTION: A zinc ion feed source and zinc dissolution accelerating metal are directly or indirectly brought into electrical contact in a galvanizing liquid in a zincate bath. The zinc ion feed source and zinc dissolution accelerating metal are continuously or intermittently oscillated, vibrated or rotated to accelerate the dissolution of zinc from the zinc ion feed source. The plating liquid comprising the dissolved zinc ions is fed to the galvanizing bath. COPYRIGHT: (C)2004,JPO
