将NiCl2·6H2O经过脱水干燥后得到的NiCl2粉末作为原料,采用化学气相沉积技术通过H2还原反应,在Al2O3陶瓷表面沉积了Ni涂层。研究了涂层的相组成、涂层与Al2O3陶瓷结合力和涂层与铜熔液间的润湿行为。结果表明:制备的涂层中的主要组分为Ni,Ni涂层均匀、致密,厚度可达40μm,且涂层与陶瓷之间的结合良好。座滴法测得沉积Ni涂层的Al2O3陶瓷与Cu之间的润湿角为30.15°,表明涂层明显改善了陶瓷与金属间的润湿性。 NiCl2 · 6H2O obtained after dehydration drying NiCl2 powder as raw material, the use of chemical vapor deposition through H2 reduction reaction, Ni coating deposited on the Al2O3 ceramic surface. The phase composition of the coating, the adhesion between the coating and the Al2O3 ceramic and the wetting behavior between the coating and the copper melt were investigated. The results show that the main components in the prepared coating are Ni, Ni coating is uniform and dense, the thickness is up to 40μm, and the bonding between the coating and ceramic is good. Droplet method measured deposition of Ni-coated Al2O3 ceramic and Cu wetting angle between 30.15 °, indicating that the coating significantly improves the wettability between the ceramic and metal.
