 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.

Abstract

In this study, plant extract (wild clary)  are tested and applied to steel (AISI l015) to prevent its corrosion in two mediums of sea water and  0.5 M HCl using electrochemical studies at three temperatures (298, 318, 338 K) by adding five concentrations of the extract (5, 10, 15, 20, 25) mL /L. The inhibition efficiency was found to be excellent, reaching 83.078% at a concentration of 20 (ml/L) and a temperature of 298 (K), which is the best concentration in seawater, and 92.944% at a concentration of 25 (ml/L) and a temperature of 298 (K) which is the best concentration in an acid medium hydrochloric.

Abstract

The aim of this study is to evaluate the possibility of using waste rubber tires as a substitute for sand and gravel. The physical and mechanical properties of rubber concrete have been tested for various sizes of rubber chopped by proportions different, so the properties that rubber concrete can gain by using this alternative are low cost, lightweight, toughness, shock absorption, and heat insulation, and preserving the environment by providing a safe solution.

Abstract

The main objective of this research is to acquire high tribological surface properties by improving the hardness and erosion resistance of alloy 2024, and to study the effect of heat and surface treatments on the hardness and erosion properties.  Several heat and surface treatments were applied.  These treatments are annealing, solution and aging treatment, plasma nitriding, and duplex surface treatment, which includes plasma sputtering followed by plasma nitridation.  The microstructure, hardness and mechanical wear resistance of this alloy were checked before and after each treatment.  An erosion tester was manufactured locally to measure the wear resistance of this alloy.  X-ray diffraction, scanning electron microscopy, and Vickers hardness were used to characterize the results.  The results showed that each treatment differently affects the microstructure, wear resistance and hardness of this alloy.

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.
