铅、碲对灰铸铁金相组织与性能的影响

Influence of Pb and Te on Microstructures and Properties of Gray Iron

研究了铅、碲对灰铸铁金相组织及性能的影响,提出灰铸铁中铅的质量分数应控制在0.003%以下,使用碲粉涂料时必须注意避免碲污染。

The influence of Pb and Te on the microstructures and properties of gray iron was inves-tigated.It was proposed that Pb content should be limited to be less than0.003%,and it is nec es-sary to avoid Te contamination from Te-containing coating.
