- •
Magnetite scales were found in naphthenic acid (NAP) corrosion.
- •
Magnetite scales were formed due to thermal decomposition of iron naphthenates.
- •
Formation and protectiveness of magnetite scales depended on structure of NAP.
- •
Carboxylic acids confirm corrosion observations for commercial NAP.
