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

摘要

This research defines the best combination of factors (water pressure, the use or non-use of washingwith 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 againstcorrosion. Results show that the epoxy/iron oxide paint had the best performance when: a water-jetting pressureof 275.8 MPa is used, followed by a low pressure freshwater cleaning. Results also show the best results whenthe process is developed at the highest environmental temperatures and lowest humidity.
