摘要
在钢表面进行固态渗硼，渗硼温度850～950℃，时间3～5h。采用扫描电子显微镜对渗层横断面进行表面形貌观察，X-射线衍射仪分析渗层的相结构，显微硬度计测试渗层各点的维氏硬度，并对基体及渗层进行快速磨损试验。结果表明：可获得厚度均匀的渗硼层，渗硼层主要由FeB和Fe2B两相组成，且渗层维氏硬度值最高达1088HV，有很高的耐磨性能。
Boronizing coatings were obtained on steel via solid state boronizing, under the following condition; the temperature of 850- 950℃ and duration of 3 -5 h. Cross-sectioned morphology and phase structure of the boronizing coatings were examined using scanning electron microscopy （SEM） and X-ray diffraction analysis （XRD） , respectively. Micro hardness measurement and rapid abrasive test were also performed. Experimental results show that, compact boronizing coatings with homogeneous thickness, whose main phases are FeB and Fe2B, can be obtained. The maximum micro hardness value of the coatings can reach 1 088 HV. The boronizing coatings also have good wear resistance.
