A METHOD OF COATING A METAL SUBSTRATE WITH A PROTECTIVE ALUMINIUM-SILICON COATING, A METAL SUBSTRATE HAVING THE COATING, AND THE USE OF THE COATED METAL SUBSTRATE

摘要

A method of coating metal substrates with a protective aluminum-silicon coating comprising a mixture of (1) an Al-Si eutectic, Al-Si hypereutectic or elemental aluminum and (2) elemental silicon, the articles of manufacture provided by said coating and the method of carrying out thermal hydrocarbon processing operations where corrosion/erosion and other high temperature interactions are a problem using apparatus containing said coatings.
