摘要

研究了不同铸渗工艺对铸钢件表面铸渗硅复合层厚度和质量的影响。采用扫描电子显微镜（SEM）、X射线能谱（EDS）及显微硬度仪等分析手段

阐述了该铸钢件表面铸渗硅复合层的微观成分、组织及性能特点。结果表明

钢水的浇注温度为1560℃左右时

铸钢件表面可以得到厚度为0·5

·3mm且表面质量较好的复合层。另外渗硅层与母材铸钢的界面为结合牢固的锯齿型冶金结合状态。

Abstract

Effects of different casting-infiltration ways on thickness and quality of Si-Fe compound layer on cast steel part surface have been conducted.Microstructure

constituent and properties of Si-Fe compound layer were determined by SEM（scanning electromicroscope）

EDS and micro-hardness tester.Desirable cast-infiltrated Si-Fe compound surface with 0.5

.3 mm in thickness can be obtained on the cast steel parts surface with pouring temperature at about 1 560 ℃ for liquid steel.In addition

the bonding mechanism of cast-infiltrated Si-Fe compound layer with matrix exhibits sawtooth-like metallurgical bonding.
