How to Select Corrosion Inhibitors for Magnesium Alloys? Prevention and Control of White Spots in AZ31 Machining
White spots on AZ31 magnesium alloy after machining result from corrosion product buildup on the base metal; prevention relies on a three-layer approach—low-chloride alkaline machining fluid management, magnesium-specific corrosion inhibitors (Vanconol® MGR-82/83, ALI-910), and inter-process cleaning/drying—with inhibitor selection matched to the machining fluid type and data verified against TDS and actual testing.
