Titanium & Alloys

Titanium and Titanium alloys are difficult to Electro-polishing due to the rapid formation of a dense non-porous surface film of titanium dioxide, which is an electrical insulator. For electropolishing to be successful, the process must include a mechanism for continuous surface renewal and removal of formed Titanium cations from the reaction zone.
Finish Line has developed a robust Electro-polishing Processes for parts of Titanium of various grades, and is well experienced in long time supply of this Electro-polishing services to its customers.
Finish Line has developed as well a Titanium Etching Process, which includes abrasive blasting pretreatment. This Process also is one of the long-run Finish Line’s processes serving its customers.
Both Titanium Electro-polishing and Titanium Etching Lines have a capacity of thousands units per day.
While supplying Titanium Electro-polishing or Titanium Etching services, Finish Line ensures high performance of surface qualities as agreed with a Customer (there are no appropriate Standards for the case). Besides, we provide solutions for specific customers’ tasks, like standing complicated and contradict dimensions demands for configurated spinal implants (view image), two-level structured micro-topography of dental implants (view image), etc. For each of these above mentioned missions, a targeted research was conducted , including academic approaches and equipment.

Anode Treatment

Anode treatment beneficiates metal surface through metal dissolving and oxidation. In case no coating is allowed, Anode Treatment is a way to enhance your parts’ surface qualities. more >>


Passivation is a classic anode treatment to improve corrosion resistance of metals, comparing to not treated parts, through completing natural formation of metal oxides surface layer. more >>

Bright Passivation

Bright Passivation improves corrosion resistance of metals, comparing to not treated parts, removes spots from previous processing and provides the parts with brighter appearance. more >>


Etching is an old craft which technically comprises a vigorous anode treatment process, widely exploited in industry. Etching metal surface as a whole makes it uniformly rough and porous more >>

Color Anodizing

Color Anodizing is a unique Titanium only applied process granting to metal surface a wide spectrum of controllable vivid interference colors, which are stable, uniform and repeatable more >>

Surface preparation

Surface preparation ensures the after Anode Treatment surface features as aimed. It includes both quality improving (like de-burring) and surface beneficiation (like surface roughening) more >>

Surface cleaning

Surface Cleaning is an essential completing operation after any Anode Treatment intended washing the surface from leftovers of previous treatment, using purified water at the end step more >>
