- 摘要:
- 采用化学镀的方法在激光选区熔化（ SLM ）技术成型的 SiCp/Al 复合材料表面制备了 Ni-P 镀层，研究了施镀时间对镀层的表面形貌、截面厚度、沉积速率、相结构和显微硬度的影响。结果表明：化学镀 0.5 ～ 12 h 时，镀层都呈胞状形貌，且呈非晶态结构，为高磷镀层；随着施镀时间的延长，胞状组织逐渐变大，表面逐渐致密，镀层厚度逐渐增大，但增长速率越来越小，显微硬度先增大后趋于稳定。施镀时间为 8 h 时的镀层表面平整、致密、连续，厚度可达 100 um ，显微硬度为 653.4 HV ，镀层与基体结合强度为 77.2 N 。
- Abstract:
- ： Electroless Ni-P coating was prepared on the surface of SiCp/Al matrix composites by selective laser melting （ SLM ） . The effects of electroless plating time on the microstructure ， thickness ， deposition rate ， phase structure and microhardness of the coating were studied. The results show that the electroless plating coating is cellular morphology ， amorphous structure and high phosphorus coating at 0.5-12 h. With the extension of plating time ， the cellular structure becomes larger ， the surface becomes denser and the thickness of the coating increases gradually ， but the growth rate becomes smaller and smaller ， and the microhardness first increases and then tends to be stable. When the plating time is 8 h ， the surface of the coating is smooth ， dense and continuous ， the thickness can reach 100 μ m ， the micro-hardness is 653.4 HV ， and the bonding strength between the coating and the substrate is 77.2 N.
