Abstract
The study aimed to enhance corrosion properties for low carbon steel surface by using flame thermal spraying technique to deposit a Ni-Cu (Monel) protective coating overlay. The optimum coating parameters were (125 mm (level 2) spray distance, 30 g (level 3) N10 powder rate, substrate surface roughness, 50 mm/min (level 2) gun carrier transverse velocity). The results of SEM show the coating layer is rich in Ni-Cu, which makes it more resistant to corrosion. XRD showed the Cu and Ni-Cu phases. The erosion rate was measured by using 3.5% NaCl solution showed the minimum weight loss (0.00166 mm/year).
The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.
