| 简介 |
Described herein are pretreatrnent compositions, coated aluminum alloy products, and methods for coating the alloys. The pretreatrnent compositions include inorganic chemical corrosion inhibitors dispersed in a silane-based matrix and may further include clay particles. The inorganic chemical corrosion inhibitors include rare earth metals and salts thereof. The pretreatrnent compositions, when applied to the surface of an alloy, inhibit corrosion of the alloys. The pretreatrnent compositions can be used in automotive, electronics, industrial, transportation, and other applications. |
