Abstract
In this article, a strategy for the fabrication of color-tuned titanium using a torch was developed. The torch was used to manufacture a layer of titanium dioxide on titanium substrates. The reaction time and requirements were reduced compared to the anodization process. Various colors appeared depending on the time of torch heating, and this torched-titanium substrate was treated with octadecyltriethoxylsilane (ODTS) to gain superhydrophobic properties for self-cleaning. Scanning Electron Microscope (SEM), Raman spectroscopy, and Atomic Force Microscope (AFM) were used for surface analysis. Besides, the mechanical and ODTS stability of the surface were evaluated through a cross-cut adhesion tape test and water contact angle measurement, proving that the torch is a suitable fabrication process for multifunctional color-tuned titanium.
Highlights
Titanium has attracted much attention in various fields such as aerospace [1], marine industry [2], electronics [3,4,5,6,7], and medical industry [8] due to its high strength, lightness, corrosion-resistance, bio-compatibility, and luxury color
The polished-titanium substrates were denoted as Ti-p1, Ti-p2, Ti-p3, Ti-p4, Ti-p5 while
As can be be seen the rubbed titanium substrates werewere denoted as Ti-s1, Ti-s2, Ti-s3, Ti-s4, Ti-s5
Summary
Titanium has attracted much attention in various fields such as aerospace [1], marine industry [2], electronics [3,4,5,6,7], and medical industry [8] due to its high strength, lightness, corrosion-resistance, bio-compatibility, and luxury color. Titanium has been used in the industrial fields and in civil and construction areas. The color of titanium was tuned by anodic oxidation by which the structure color of anodized-titanium showed various colors, like a chameleon, concerning changes in the angle of sunshine [9]. To obtain various titanium colors, various thicknesses of titanium oxide layers are required [10,11,12]
