Corrosion resistance of functionalized carbon nanotubes enhanced epoxy coatings on sintered NdFeB magnets
Abstract In this work, tannic acid (TA) was employed to modify the surface of multiwall carbon nanotubes (CNTs) to form TCNTs hybrids via noncovalent functionalization to enhance its dispersibility in water. Then, the TCNTs enhanced epoxy coatings were applied on sintered NdFeB magnets by cathodic e...

| 520 | |a Abstract In this work, tannic acid (TA) was employed to modify the surface of multiwall carbon nanotubes (CNTs) to form TCNTs hybrids via noncovalent functionalization to enhance its dispersibility in water. Then, the TCNTs enhanced epoxy coatings were applied on sintered NdFeB magnets by cathodic electrophoretic deposition method for corrosion test. The corrosion resistance of prepared specimens was assessed by electrochemical experiments. The results show that TCNTs hybrids present a more homogeneous distribution in epoxy resin than pristine CNTs and could obviously promote anticorrosion properties of prepared specimens. Within 36-day soaking in 3.5 wt.% NaCl solution, the specimens maintain a high value of |Z|0.01Hz ($ 10^{8} $ Ω $ cm^{2} $) when the concentration of TCNTs is 2 g/L. When immersed in 3.5 wt.% NaCl solution for 40 days, the Ecorr of specimens shifts to − 0.207 V and Jcorr is about 5.281 × $ 10^{−11} $ A $ cm^{−2} $, which demonstrates superior corrosion resistance. | ||

Then, the TCNTs enhanced epoxy coatings were applied on sintered NdFeB magnets by cathodic electrophoretic deposition method for corrosion test. The corrosion resistance of prepared specimens was assessed by electrochemical experiments. The results show that TCNTs hybrids present a more homogeneous distribution in epoxy resin than pristine CNTs and could obviously promote anticorrosion properties of prepared specimens. Within 36-day soaking in 3.5 wt.% NaCl solution, the specimens maintain a high value of |Z|0.01Hz ($ 10^{8} $ Ω $ cm^{2} $) when the concentration of TCNTs is 2 g/L. When immersed in 3.5 wt.% NaCl solution for 40 days, the Ecorr of specimens shifts to − 0.207 V and Jcorr is about 5.281 × $ 10^{−11} $ A $ cm^{−2} $, which demonstrates superior corrosion resistance.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">NdFeB magnets</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Carbon nanotubes</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Tannic acid functionalization</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Epoxy coatings</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Corrosion resistance</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Duan, Liangsong</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Zhang, Pengjie</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Xu, Guangqing</subfield><subfield code="0">(orcid)0000-0003-2581-3780</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Cui, Jiewu</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Lv, Jun</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sun, Wei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Li, Bingshan</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wang, Dongmei</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Wu, Yucheng</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of coatings technology and research</subfield><subfield code="d">Springer US, 2004</subfield><subfield code="g">19(2022), 5 vom: 14.

Corrosion resistance of functionalized carbon nanotubes enhanced epoxy coatings on sintered NdFeB magnets |
| abstract |
Abstract In this work, tannic acid (TA) was employed to modify the surface of multiwall carbon nanotubes (CNTs) to form TCNTs hybrids via noncovalent functionalization to enhance its dispersibility in water. Then, the TCNTs enhanced epoxy coatings were applied on sintered NdFeB magnets by cathodic electrophoretic deposition method for corrosion test. The corrosion resistance of prepared specimens was assessed by electrochemical experiments. The results show that TCNTs hybrids present a more homogeneous distribution in epoxy resin than pristine CNTs and could obviously promote anticorrosion properties of prepared specimens. Within 36-day soaking in 3.5 wt.% NaCl solution, the specimens maintain a high value of |Z|0.01Hz ($ 10^{8} $ Ω $ cm^{2} $) when the concentration of TCNTs is 2 g/L. When immersed in 3.5 wt.% NaCl solution for 40 days, the Ecorr of specimens shifts to − 0.207 V and Jcorr is about 5.281 × $ 10^{−11} $ A $ cm^{−2} $, which demonstrates superior corrosion resistance. © American Coatings Association 2022 |
