摘要
通过脉冲电沉积技术制备出含1,4-丁炔二醇或糖精为添加剂的Al2O3/Ni-Co复合材料,采用TEM、EDS等方法分析了含2种添加剂的Al2O3/Ni-Co复合材料的微观组织结构,比较了添加剂对材料光洁度、显微硬度、室温塑性以及高温塑性的影响,并通过SEM对变形后材料的显微结构进行了表征。以糖精为添加剂所制备的Al2O3/Ni-Co的硬度最高可达HV469,断裂强度达1150 MPa,室温延伸率达7%,超塑性延伸率达417%。
The Al2O3/Ni-Co composites with different additives were fabricated by pulse current electrodeposition,the microstructures of Al2O3/Ni-Co composites were studied by TEM and EDS.The effects of additives on the smoothness,microhardness,plasticity at room temperature and at high temperature were compared.SEM was employed to examine the microstructures of the deformed samples.The hardness,fracture strength,elongation at room temperature and at superplastic temperature of the Al2O3/Ni-Co composite reach HV469,1150 MPa,7% and 417% respectively,when the saccharin was used as additive.
