Résumé : |
In this article, the authors illustrate a comparison between a new flexible version of an abrasion-resistant overcoat (ARO) coating system and two ARO coatings at a total thickness of 20 mils, two single-layer fusion-bonded epoxy (FBE) coatings, and two dual-layer FBE (2LFBE) systems at a thickness of 60 mils. |

- FIGURES : 1. For this set of tests, a profilometer measured a peak to valley height of 70-to-100 µm (~3 – 4 mil) and an average peak count of 41/cm (104/in) - 2. Both the short- and long-term CD tests were conducted at 65 C (150 F), -3.5 V (calomel reference electrode) and a 3-percent NaCl electrolyte - 3. Short-term cathodic disbondment results - 4. Long-term cathodic disbondment results - 5. A crack on a bended sample under 40 times magnification. Any coating crack seen at 40 times magnification constituted a failure - 6. While the flexible ARO layer showed a low level of porosity, almost none was seen in the remaining samples for either layer - 7. Average passing impact resistance results
- TABLES : 1. Different coating thickness systems for the tests - 2. Average flexibility results for different mandrels - 3. Average hot water soak adhesion results - 4. Average porosity ratings of coating layers - 5. Test averages according to coating type |
