使用稀土基涂料和稀土镁基涂料实现了灰铸铁件表面层石墨的球化, 在原铁水不同的碳当量和含硫量的情况下, 分析和比较了使用不同涂料处理的灰铸铁表面层的石墨形态和基体组织的变化规律, 以及结晶凝固冷却曲线.
The rare earth-based coatings and rare earth-based magnesium-based coatings were used to realize the spheroidization of graphite on the surface of gray cast iron. In the case of different hot metal equivalent carbon content and sulfur content, the graphite layers of gray cast iron treated with different coatings were analyzed and compared Morphology and matrix changes in the law, as well as crystalline solidification cooling curve.
