摘要：
A corrosion resistant pretreatment composition for coating a metal substrate is provided. The composition comprises an aqueous carrier, one or more Group IA metal ions, wherein at least one of the Group 1A metal ions comprises a lithium compound, a hydroxide; and a phosphate or a halide. A process for treating a metal substrate with a lithium based coating is also provided, as well as a process for treating a metal substrate with a non-chrome conversion coating process.
