Improved corrosion protection for aluminium tanks - for food, consisting of flame-sprayed aluminium alloy coating

摘要

Tanks of 99.5% Al, used in the food industry and subject to stress from thermal cycling, are blast cleaned on their inner surfaces, partic. with corundum, and are then coated by thermal spraying with a corrosion-resistant Al alloy, partic. AlMg5. Micropores in the coating are closed by brushing or sealing. ADVANTAGE - Corrosion protection is improved.
