Assessment of the Technological and Environmental Factors Influencing the Ultra-High-Pressure Water Jetting Treatment of the Surface of Naval Construction Steel Against Corrosion

Abstract

This research defines the best combination of factors (wáter pressure, the use or non-use of washing with fresh water after process, environmental factors (i.e., temperature, humidity, etc.) and type of epoxy Paint) for the high pressure water jetting treatment of naval steels to guarantee the best performance against corrosión. Results show that the epoxy/iron oxide Paint had the best performance when: a water-jetting pressure of 275.8 MP a is used, followed by a low pressure freshwater cleaning. Results also show the best results when the process is developed at the highest environmental temperatures and lowest humidity.
