Kahdim}, journal={DIYALA JOURNAL OF ENGINEERING SCIENCES مجلة ديالى للعلوم الهندسية}, volume={13}, number={4}, pages={1-9}, year={2020}, abstract={This study investigates how microstructure and chemistry effects by Nano-Metal-Phosphate and the kinetics of growth passive layer and passivity breakdown. Additionally, the passive layer germination behavior on aluminum alloy 1050 with anticorrosive properties. The passive layer is an alloying method which allows an aluminum oxide to germinate. Morphologically and structurally, the aluminum oxide films were characterized using microscopy analyzes and XRD analysis. Results indicated that the reinforcements are well distributed and the grin size is downy. Corrosion behavior tested by Cyclic polarization exam and done at room temperature in (3.5 per cent NaCl) solution. The reinforcement increased the hardness for processed aluminum from Hv81.1 to HV=120.492 as castings. The parameter Nano-Metal-Phosphate has attenuated the current density of corrosion (7.15μA / cm2) compared to the as-cast sample results.
