摘要
采用座滴法研究了Ni对Al/ZTA界面润湿性的影响。结果发现,Ni元素能够有效改善Al/ZTA的界面润湿性,同样温度条件下,Al/ZTA界面润湿角为88°,而Al/Ni/ZTA界面润湿角为61°。进一步深入研究发现,铺展动力是Ni元素向Al发生扩散,在Al中形成中间化合物。又以Ni基合金作为过渡层制备了ZTA颗粒增强Al基复合材料,界面间结合良好,该复合材料具有低密度、耐磨损的特性。
The influence of Ni coating on the interface wettability of Al/ZTA was investigated using a sessile drop method.The results show that Ni can improve the interface wettability of Al/ZTA effectively.The contact angle of Al/ZTA is 88°,while under the same temperature condition the contact angle of Al/Ni/ZTA is 61°.More intensive study shows the driving force of drop spreading is the diffusion from Ni to Al along with the intermetallic forming in the Al drop.For the purpose of manufacturing the ZTA particle reinforced Al matrix composites,Ni alloy is used as transition layer,which exhibits the characteristics of compact interface bonding,low density and fine wear resistance.
