英文摘要: Abstract(#br)The present study discusses the effect of the electrolyte on the growth of an oxide layer on NiTi alloy via anodic treatment with the aim of understanding the surface reactions that occur during the anodization process. For this purpose, anodic treatments of NiTi substrates were conducted using H 3 PO 4 , H 2 SO 4 , and HNO 3 electrolytes in concentrations ranging from 1 to 100mM. Surface analysis using XPS revealed that for all the three electrolytes, a TiO 2 layer containing a small amount of Ni was formed on the anodized surface; however, the type of electrolyte influenced the thickness of the oxide layer formed. Using 100mM HNO 3 as the electrolyte was the most advantageous condition to obtain a thick oxide layer (thickness ~...
