研究了D型石墨的数量及Si／C对金属型D型石墨铸铁在700～900℃范围内氧化速度的影响；对比了成分相同的D型石墨铸铁和A型石墨铸铁的抗氧化性能；探讨了金属型D型石墨铸铁的抗氧化机理，结果表明，金属型D型石墨铸铁具有优良的抗氧化性能。
The effects of D type graphite and Si / C on the oxidation rate of metallic D type graphite cast iron at 700-900 ℃ were studied. The oxidation resistance of D type graphite cast iron and A type graphite cast iron with the same composition were compared. The anti-oxidation mechanism of the metallic D-type graphite cast iron shows that the metallic D-type graphite cast iron has excellent oxidation resistance.
