Metals We Treat

Differencies in atomic and crystalline structure of metals result in their different polarization when immersed into an elctrolyte bath, which may be so significant, that at the same electrolyte bath one metal becomes anode, while another becomes cathode. The differencies occur even more complicated, when treating metal alloys, which actually are the practical cases. The task turns yet even more complicated when matching elctrolyte to special requierements of a working part.


These differencies lead to necessity to develop a specific electrolyte for every metal, and to match it consequantally to every alloy, and then to configurate process parameters for every specific part.


Finish Line developed, elaborated and/or matched appropiate electrolytes for all its Anode Treatment Processes, in frames of theoretical limits, for all metals it faced surving the customers: Stanless Steels (both Austenitic and Martencitic), Titanium, Nitinol, CoCr Alloys, Aluminum and Copper, and few “exotic” metals, like Zirconia and Tantalum.


Stanless Steels (both Austenitic and Martencitic), Titanium and Nitinol parts are at a high market demand for anode treatment processing, and these metals are treated at the Company’s lines at industrial scale of up to thousands units per day.


CoCr Alloys, Aluminum and Copper Anode Treatment Processes are validated at the Company on pilot scale, and may be operated at full industrial scale, subject to previous adjusting to specific requirements of a customer.


Finish Line is capable to develop/adjust any needed Anode Treatment Process for any metal or alloy for specific customers’ items, following practical marketing needs.

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

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

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 >>

Clean Room Packing

Packing in Clean Room class 1000 with laminar cameras class 100 allows us to implement packaging procedure for customers’ products having the highest cleanness requirements more >>
