How to Polish Titanium | 8 Polish Ways
After the fabrication of titanium parts, the final step is how to shine the titanium surface finish to give a titanium mirror-like polished surface. Titanium polishing is also done by metallurgically to see the microstructure analysis of the titanium. Titanium polishing uses tools like abrasive media to remove oxide surfaces, belts, and wheels. After the polishing is done, additional surface restoration process can be carried out like duffing of titanium to achieve a perfectly desired surface.
Polishing the titanium surface helps in improving intrinsic properties like corrosion resistance, strength, biocompatibility, and wear resistance. Titanium alloys with surface finish reduces the surface roughness and increase the physical appearance with additional protection and a better surface finish.
Titanium Alloys Easy to Polish?
Titanium and its alloy have certain properties that make it difficult to polish and anisotropic. Anisotropic behavior means its properties changes in different direction and also microstructure changes create an alpha-phase mechanical twinning which makes it challenging to have uniform mechanical properties and surface finish during polishing. Also, its highly stability, chemical resistance layer and hard TiO2 make it difficult to remove by mechanical or chemical polishing.
Can you Polish Titanium
Yes, titanium polishing is difficult but can be done through different processes mechanical polishing, electropolishing, vibratory polishing, lapping, plasma polishing, and diamond polishing. This article will help you understand all of these titanium finishing processes in detail.
Polish Titanium Tools and Equipment
Titanium surface finishing includes different steps and every step required unique tools and equipment depending on the process you choose.
Rotatory tools like polishing pads, abrasive wheels, brushes, sisal, cotton polishing wheels, buffs for buffing titanium. Special abrasive polishing compounds are used to achieve mirror polish titanium. It is made from the diamond because of its hardness. Due to high hardness of diamond paste, it can easily remove the TiO2 layer from the titanium surface. Sandpaper and abrasive sheets as well as lapped films of controlled particle size are used to gradually decrease the roughness of titanium. The diamond polishing pad is used with water as lubricant attached to rotary tools. For electroplating special tools and solutions are used for ultrasonic cleaning i.e., high-frequency sound wave ultrasonication is required in titanium cleaning method.

Mechanical Polishing
Metal polishing technique known as Mechanical polishing is considered the best polishing method for titanium gloss restore including grinding and buffing of titanium which help in the removal of gouges, damaged rappers, deformations, and scratches from the surface. Titanium surface polishing helps the surface to increase its wear and corrosion resistance as well as fatigue life of the material.
- To shine titanium first, the surface dust, grease, or any other contamination is removed from the surface by normal washing with DL water-ethanol or acetone. In the case of deep cleaning, ultrasonic bath cleaning can also be done for 2 to 3 minutes.
- Dry the surface completely, either leave it until dry or use a blow drier.
- Rough polishing is done initially with coarse abrasive grade paper and then moves to fine grades (600-2000 grade sandpaper papers) with the help of buffing wheels for buffing titanium.
- Again, the sample is washed through DL water and dried.
- Then, neat polishing is done to shine the titanium and to retore its gloss by using cotton fiber or nylon cloth attached on buffing wheels with diamond lubricant until the mirror-polished titanium surface is achieved.
- To shine titanium, wash with water several times and dry it. A smooth and clean titanium surface is prepared.

Electropolishing
This titanium finishing process uses an electrochemical reaction to remove surface impurities. The electrochemical cell is arranged in which titanium which has to be polished is connected to the anode (positive terminal) of the cell while the cathode is attached with either conducting material like stainless steel and this metal is selected from the electronegativity chart. The acidic electrolytic solution is filled in the cell. Usually, very rough surfaces with deep cuts have to be first mechanically polished and then electropolished. Electropolish is a fast, efficient, and controllable method that provides uniform and high-quality shine by restoring the gloss of titanium surface.

Vibratory Polishing
In this titanium cleaning method, titanium surface restoration after fabricating a part is done by a vibratory tumbler. It is placed in a vibratory tumbler with an abrasive media and water. The vibration in vibratory timber causes metal parts to rub against the media until the whole surface is polished and shines. After that final cleaning and drying may have to be done. The titanium part which has to be polished, is placed in a vibratory tumbler with an abrasive media and water for a smoother finish. The vibration in vibratory timber cause metal parts to rub against the media until the whole surface is polished and shines.
After that final cleaning and drying may have to be done to completely restore the gloss of titanium. It uses a centrifugal high-energy machine with the walnut shell, which is pretreated. This process gives you a titanium shine surface with reduced surface roughness and defect removal. In this process, no special tooling is required and no part specification is required. It can offer an internal and external polishing for the smoother finish of hollow surfaces to provide you consistency and repeatable results.

Diamond Polishing
How to shine titanium in the best way the answer is to use diamond particles to polish because they are hard and can remove the TiO2 layer in order to fully restore the gloss of titanium. Buffing, cleaning, shining and surface restoration of titanium all can be done best with monocrystalline diamond paste which is effortless and time-saving machining to get mirror polish titanium surface. The high concentration of diamond allows a mirror polish finish with maximum surface restoration with low paste consumption. This titanium finishing process ensures uniform grain size and allows working in two steps. These diamond pastes are soluble in water oil and alcohol. These pastes are stable at temp up to 130°C which help in attaining a maximum smoother finish to the product .
Plasma Polishing
How to shine titanium with plasma metal polishing method? In this titanium surface finish process, material is subjected to a high-energy plasma environment to get surface restoration and a smoother surface finish. The surface is bombarded with ions which are reactive species that cause the removal of the thin surface layer of titanium. This titanium finish process includes low material waste and preserves material integrity. As ion selectively etch the surface and remove dust, defects, and scratches. This is not only clean the titanium bus but also restores the gloss and provides an excellent smoother surface finish.
