摘　　要：针对电解槽阳极钢爪在高温和电解质冲刷下的氧化腐蚀问题,提出了采用纳米陶瓷基抗氧化复合材料涂层进行防护的技术。该技术显著提高了钢爪的高温抗氧化和耐腐蚀能力,延长了使用寿命,且对原铝质量影响甚微。通过试验证明,涂层技术能使钢爪使用寿命延长约28个月,经济效益显著,具有广阔的市场应用前景。A nano ceramic based antioxidant composite material coating is proposed to protect the anode steel claws of electrolytic cells from oxidation and corrosion under high temperature and electrolyte erosion.This technology significantly improves the high-temperature oxidation resistance and corrosion resistance of steel claws,prolongs their service life,and has little impact on the quality of primary aluminum.Through experiments,it has been proven that coating technology can extend the service life of steel claws by about 28 months,with significant economic benefits and broad market application prospects.
