Users Guide

To reach the best EP results, we advice to a User to implement some practical guide lines:

• Choose right materials. Titanium, Nitinol, high Ni-Cr St Steels which are C-Si-S free – these metals have a good chance of lustrous EP, while the presence of metalloids in the metal, or using of not alloyed steels, need special consideration of the electro-polisher, and results are not for grant.

• The history of the metal treatment is of crucial importance for the EP results. If you want them best, consult your electro-polisher for choosing pre- and post machining treatment, including stages made by supplier of the metal, and take his considerations in account.

• Take in account quality tolerances of metals. Sometimes, metal quality deviations, or hidden surface defects, may be resulted in bad electro-polish.

• Geometry and dimensions of the part have considerable influence on the EP results. Parts of the same material behave differently when having different geometry and dimensions. Spare time for tests.

• Analyze and define as exactly as possible your requirements to parts after EP; use references and control samples and consult your electro-polisher;

• Remember that for any EP effect you “pay” by dimensions of the treated part. Thumb rules: to reach uniform brightness, EP has to remove few microns from the machining part of high finishing, and up to 30 microns from the machining part of low finishing; to dissolve light burrs, EP has to remove 10 microns, and for heavy burrs up to 50 microns must be removed; to discolor light oxide spots, EP has to remove 5 microns, up to 30 microns for heavy oxidation; to smooth scratches, EP to has to remove five times more thickness than the deepness of the scratches; every 10 microns of removed thickness add 1 micron to tolerance.

• A skilled electro-polisher will supply you with the best solutions, including complicated cases, just consult him and ask him for tests at the earliest stage you can.

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 >>
