Research on Surface Nano-ceramic on Aluminum Alloy by Electron Beam Scanning
Author(s): 
Pages: 61-63,65
Year: Issue:  8
Journal: Hydraulics Pneumatics & Seals

Keyword:  电子束扫描铝合金纳米陶瓷化;
Abstract: 电子束表面处理可以提高铝合金材料的表面硬度和耐磨性.本研究利用电子束扫描对铝合金表面添加Al-Al2O3混合纳米粉进行表面强化处理,对铝合金电子束改性试样陶瓷层组织特征和金相结构进行分析,并对铝合金陶瓷层的硬度和耐磨性进行试验测试.实验结果表明:铝合金电子束表面处理后,能够得到5mm的陶瓷层,同时生成了复杂化合物和新的相,陶瓷层与基体材料间有重熔组织;铝合金电子束表面处理后显微硬度得到提高,是基体...
