Improvement of AZ91 Alloy Corrosion Properties bynDuplex NI-P Coating Deposition

Popis výsledku v původním jazyce

The corrosion behavior of duplex Ni-P coatings deposited on AZ91 magnesium alloy wasnstudied. The electroless deposition process of duplex Ni-P coating consisted in the preparation ofnlow-phosphorus Ni-P coating (5.7 wt.% of P), which served as a bond coating and high-phosphorusnNi-P coating (11.5 wt.% of P) deposited on it. The duplex Ni-P coatings with the thickness of 25, 50,n75 and 100 m were deposited on AZ91 magnesium alloy. The electrochemical corrosion behaviornof coated AZ91 magnesium alloy was investigated by electrochemical impedance spectroscopynand potentiodynamic polarization method in 0.1 M NaCl. Obtained results showed a significantnimprovement in the corrosion resistance of coated specimens when compared to uncoated AZ91nmagnesium alloy. From the results of the immersion tests in 3.5 wt.% NaCl, 10% solution of HCl andnNaOH and 5% neutral salt spray, a noticeable increase in the corrosion resistance with the increasingnthickness of the Ni-P coating was observed.
