| 英文摘要 | anti-corrosive coatings based on layered double hydroxides (ldhs) have been considered as promising alternatives to conventional chromate-containing conversion coatings. among various ldhs, carbonate-intercalated ldh coatings with a c-axis preferred orientation should be the optimum structure for protecting metals against corrosion. herein we successfully prepared nial-co3 ldh coatings on aluminium plates in one step. particularly it was found that co2 dissolved in the precursor solution exerted great influence on the microstructure and anti-corrosion capacity of prepared ldh coatings. trace amounts of co2 in the precursor solution led to the formation of ab-oriented 7 mm-thick ldh coatings, while preferentially c-oriented ldh coatings with an average thickness of 12 mm were formed from co2-saturated precursor solutions. a dc polarization test demonstrated that preferentially c-oriented ldh coatings exhibited much higher anti-corrosion performance than ab-oriented ldh coatings possibly due to the decreased density of mesoscopic defects. simultaneously, co2, the green gas, was also positively utilized. |
