The morphology and adhesion strength of the autocatalytic electroless nickel phosphorus (Ni-P) film, deposited at 40 ºC on polished alumina (Al 2 O 3 99.6%) substrate, pretreated by sulfur/nitric solution, sensitizing with acid stannous chloride and activated using palladium chloride solutions, was studied using contact angle (CA), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), mechanical profilometer (DekTak), and direct laser writer (“maskless lithography”). The results showed that after treatment of the polished Al 2 O 3 substrate, it presented a high performance in the electroless deposition of Ni-P thin-film at low temperature (40 ºC). It was obtained a more compact and continuous film, with small grain size and strong adherence.
在 40 ºC 下沉积在抛光氧化铝（Al 2 O 3 99.研究使用了接触角 (CA)、扫描电子显微镜 (SEM)、能量色散光谱 (EDS)、机械轮廓仪 (DekTak) 和直接激光写入器（"无掩模光刻"）。结果表明，经过处理的抛光 Al 2 O 3 基底在低温（40 ºC）下无电沉积 Ni-P 薄膜时表现出很高的性能。获得的薄膜更紧凑、更连续，晶粒更小，附着力更强。
