摘要
采用激光熔化同步输送的Al/B_4C复合粉末,在45#钢基体上制得Al/B_4C多层熔覆层,其组织致密均匀,B_4C颗粒大部分已分解,有两种针状相生成并均匀分布在铝基体上,经分析可知是Al_4C_3及AlB_(12)C_2。熔覆层具有较高的硬度。
Al/B4C composite layer is fabricated with a Laser Direct Deposition set,of which the microstructure is dense and uniform . Mostly B4C particles have decomposed and formed two kinds of needle phases distributed e-venly on Al substrate which are Al4C3 and AlB12C2. The obtained layer is very hard.
