“…Apart from typical damage in the form of cracks, these phenomena can cause a reduction in the cross-section of the elements. These factors make it necessary to use protective coatings on the steel surfaces, which improve the corrosion and wear resistance [6,7].…”

The Abrasive Wear Resistance of Coatings Manufactured on High-Strength Low-Alloy (HSLA) Offshore Steel in Wet Welding Conditions

Some marine and offshore structure elements exploited in the water cannot be brought to the surface of the water as this will generate high costs, and for this reason, they require in-situ repairs. One of the repair techniques used in underwater pad welding conditions is a wet welding method. This paper presents an investigation of the abrasive wear resistance of coatings made in wet welding conditions with the use of two grades of covered electrodes—an electrode for underwater welding and a commercial general use electrode. Both electrodes were also used for manufacturing coatings in the air, which has been also tested. The Vickers HV10 hardness measurements are performed to demonstrate the correlation in abrasive wear resistance and the hardness of each specimen. The microscopic testing was performed. For both filler materials, the coatings prepared in a water environment are characterized by higher resistance to metal–mineral abrasion than coatings prepared in an air environment—0.61 vs. 0.44 for commercial usage electrode and 0.67 vs. 0.60 for underwater welding. We also proved that in the water, the abrasive wear was greater for specimens welded by the general use electrode, which results in a higher hardness of the layer surface. In the air welding conditions, the layer welded by the electrode for use in the water was characterized by a lower hardness and higher resistance to metal–mineral abrasion. The microstructure of the prepared layers is different for both the environment and both electrodes, which results in abrasive wear resistance.

“…The application of suitable corrosion protection methods for the protection of the steel structure is, therefore, a preposition for the durability of the structures. Protection methods include basically cathodic protection, steel allowances, and coatings . Another challenge is the location of the structures far offshore, which leads to restrictions for inspection and repair, namely of deteriorated coatings.…”

“…Protection methods include basically cathodic protection, steel allowances, and coatings. [1][2][3][4] Another challenge is the location of the structures far offshore, which leads to restrictions for inspection and repair, namely of deteriorated coatings. Therefore, repair coatings for OWEA shall meet a number of requirements, namely the following: high corrosion protection performance, less demands on surface preparation and climate during application (surface tolerant), application in one layer, UV resistance, precise pre-metering, and controlled mixing on site.…”

Three surface preparation methods, namely dry blast‐cleaning, grinding, and impact brushing, are applied for the preparation of steel substrates prior to the application of four different repair coating systems. The relationship between surface preparation method, coating type, coating thickness, and corrosion protection are systematically investigated with statistical methods. DoE (design of experiments) and ANOVA (analysis of variance) are used to rank the parameter effects. The repaired systems are exposed to the cyclic offshore aging test according to ISO 20340. Response parameters are rust creep and pull‐off strength. Coating system as well as surface preparation method show extreme statistical significance and have a high influence on the rust creep as well as on the pull‐off strength. Extremely significant interaction between the two factors could be found for the pull‐off strength only. Optimization calculations based on a desirability function approach (DFA) reveal that a combination of dry blast‐cleaning and lower coating thickness provided the best protection performance. If dry blast‐cleaning is not feasible, a higher coating thickness is recommended in order to maximize the corrosion protection performance.

“…Das zu prüfende System ist in Bild 2 dargestellt; es setzt sich zusammen aus Substrat (Beschichtung), Haftvermittler, Klebstoff und Halter. Als Substrate für die Klebeverbindungen kamen drei typische Deckschichtsysteme für Offshore‐Anwendungen [4–6] bzw. für Anwendungen an Überwasserschiff‐/Deckbereichen zum Einsatz [7, 8].…”
