Anti-Corrosive Properties of sol-gel hybrid coatings on the Zn alloyed plated steel

​

Recently, silane surface treatment has evolved as a promising alternative for toxic chromate-based treatments in metal-finishing industries [1-2]. The studies concerning corrosion protection of metals using silane films have invariably demonstrated that silanes, a group of environmentally compliant chemicals, could efficiently protect metals against different forms of corrosion in two major mays, That is, (1) a single silane film can protect metals against corrosion without topcoats for 6 months to 1 year, and (2) silanes can also be used in surface pretreatments of metals before painting.
