【摘要】 在不锈钢、纯铜及铝合金上 ,采用溶胶 -凝胶浸渍提拉法可制作连续的对金属起保护的 Si O2 、Ti O2 、Al2 O3及Si O2 - Ti O2 陶瓷涂层。通过阳极极化曲线、循环动电位极化曲线、点蚀电位、三氯化铁腐蚀试验、5 %硫酸腐蚀试验及氧化试验研究了陶瓷涂层对金属的保护性能。结果表明 ,这些陶瓷涂层大大提高了基体金属的耐蚀性及抗氧化能力。更多还原

【Abstract】 The ceramal coating on Copper, aleeminum alloy and stairless steel wes prepared by sol gel dipping process. The corrosion resistance of ceramal coatings was studied by pllarization curve and pltting potential determinations, Ferric chlovide test, 5% H2SO4 test and oxidation test if phowed that the ceremol coating could increse the corrosion resistance obvionsly.更多还原
