Can you polish titanium?
Yes, we can. Titanium alloy can be polished. Etermetal can polish different types of titanium products, such as titanium plates, titanium rods, titanium machined parts and other titanium components. Polishing is the process of removing the defects and inhomogeneity of the titanium alloy surface, improving the surface finish and flatness. The main purpose of titanium alloy polishing is to improve the surface quality and aesthetics, while also to improve the corrosion resistance and biocompatibility of the surface.
How does titanium looks like after polish?
This image shows different titanium parts Etermetal supplied to customers according to the requirements. The bigger one is mirror polished titanium and the smaller titanium plate was metal burshed surface. Not only these parts can be polished, but also other titanium compents can be polished according to order. If you have any project need polished titanium parts , please do not hesitate let us know. We are glad to cooperate with you to find a solution.
The polished titanium alloy can exhibit the following characteristics:
Surface quality improvement: the polished titanium alloy surface has high brightness, good smoothness, defects and inhomogeneity are effectively removed, and the overall surface quality is significantly improved.
Hardness and corrosion resistance enhancement: The polishing process helps to form a more dense oxide film on the titanium alloy surface, thus improving its surface hardness and corrosion resistance.
Higher reflectivity: after electropolishing and other processes, the surface reflectivity can be significantly improved, showing a brighter silver white, enhancing the beauty.
Easy to clean and maintain: the polished titanium alloy surface is smoother, not easy to accumulate dirt and impurities, so it is easier to clean and maintain.
How do you polish titanium?
Titanium alloy polishing methods generally include mechanical polishing and chemical polishing two kinds:
Mechanical polishing: including coarse throw, medium throw, fine throw and mirror polishing and other steps. Use the hemp wheel or wool wheel for titanium alloy to finish the product smooth; finish the coarse polishing wheel or fine wool wheel for titanium alloy to remove the grain left by rough polishing and the brightness of the product surface; throw the cotton wheel for titanium alloy and the fine wax for titanium alloy to make the titanium alloy product reach high brightness.
Chemical polishing: through the redox reaction of the metal in the chemical medium to achieve the purpose of leveling and polishing. Its advantages are that chemical polishing and the hardness of the metal, polishing area has nothing to do with the shape of the structure, all the parts in contact with the polishing fluid are polished, without special complex equipment, easy to operate, more suitable for the polishing of complex structure titanium denture bracket. However, the process parameters of chemical polishing are difficult to control, and it requires that the denture can have a good polishing effect without affecting the accuracy of the denture.
In addition, there is a method of electropolishing, which can greatly reduce the surface roughness of the titanium alloy, the reflectivity will be significantly improved, and the color will also be improved, showing a brighter silver white.
