TREATMENT FOR IMPROVED MAGNESIUM SURFACE CORROSION-RESISTANCE

摘要

A method, a composition and a method for making the composjtion for increasing the corrosion resistance of a magnesium or magnesium al1oy surface is disclosed. The composition is a water/organic solution of one or more hydrolyzed silanes. By binding silane moieties to the magnesium surface, an anti-corrosion coating on a magnesium workpiece is produced. A complementary method, composition and method for preparing the composition for treating a metal surface to increase corrosion resistance is disclosed. The composition is an aqueous hydrogen fluoride solution with a non-ionic surfactant.
