... ABSTRACT In order to develop the deep-sea cold seep simulation device, the NiCrMo/Al 2 O 3 -20%TiO 2 (P7113) coating were deposited on 20MnNiMo steel by atmospheric plasma spraying (APS), and the coating was treated with an organosilane sealing agent for pore sealing. In this study, the APS...

... process. Conversely, the support structures in deeper waters may experience slower corrosion rates due to lower oxygen levels, though fluctuating oxygen can still challenge material selection and protection. Thus, effective corrosion protection mechanisms such as coatings are essential to ensure longevity...

... ABSTRACT The painted coating serves as the initial layer of protection for the hull, making the study of cavitation erosion for the painted coating under cavitation bubbles essential for improving the hull's resistance to such degradation. We utilized ultrasonic cavitation bubbles to simulate...

... ABSTRACT This paper presents hydrogen embrittlement data on small scale test specimens machined from a recent production API 5L X65 pipe and tested under high pressure hydrogen gas. Specimens were coated and uncoated to interrogate whether masking may influence hydrogen embrittlement...

... al., 2023). In addition to cathodic protection, OWFs deployed in the highly corrosive marine environment are also coated with corrosion protection coatings to avoid corrosion damages (Momber and Marquardt, 2018). Although corrosion protection coatings are commonly designed to last for a lifetime...

... coatings are often favoured as they provide a cost-effective solution although they are subject to high compressive stresses compared to a dry insulation system. However, modelling such polymeric materials is a challenge due to their complex structure and mechanical analysis often ignores the layer...
