摘要

研究了硼在 AISI 1050 钢中的扩散动力学。在 850、900 和 950°C 温度条件下，使用 Ekabor-II 型硼化粉末，通过粉末包硼化方法对 AISI 1050 钢样品进行了 2、4 和 6 小时的硼化处理。粉末包硼化后，在试样表面获得了约 25.4 - 118.9 μm 厚的 FeB/Fe2B 硼化物层。硼化物层具有典型的齿状形态，硬度为 1071 - 1460 HV0.1。AISI 1050 钢在 850、900 和 950°C 的硼化温度下的生长速率常数分别为 1.522 × 10 -12、2.964 × 10 -13 和 6.354 ×10 -12 m2 - sec -1 。AISI 1050 钢中的硼扩散活化能为 162.93 kJ - mol -1。

Growth Kinetics and Microstructure of Iron Boride Layers on AISI 1050 Steel

Diffusion kinetics of boron in AISI 1050 steel is investigated. AISI 1050 steel samples are borided for 2, 4 and 6 h at 850, 900 and 950°C by the powder-pack boriding method using Ekabor-II boriding powder. After the powder-pack boriding, about 25.4 – 118.9 μm thick FeB/Fe₂B boride layers are obtained on the surfaces of the samples. The boride layers have a typical tooth morphology and their hardness is 1071 – 1460 HV_0.1. The growth rate constants for the boriding temperatures of 850, 900 and 950°C for the AISI 1050 steel are determined to be 1.522 × 10 ^–12, 2.964 × 10 ^–13 and 6.354 ×10 ^–12 m² · sec ^–1, respectively. The boron diffusion activation energy in the AISI 1050 steel is 162.93 kJ · mol ^–1.
