OX-Ti – Decorative Titanium Anodizing

OX-Ti is a surface anodizing treatment for titanium alloys which creates a thin compact titanium oxide layer.

Main properties of titanium anodizing


Various obtainable colours
Various bright colours can be obtained which are scratch resistant. These are obtained by self-colouring the titanium oxide layer without using pigments or inks. The colours can be used as colour codes to quickly identify similar parts.

Biocompatible
Thanks to its high chemical resistance, the biological compatibility of the layer and the absence of pigments, medical parts can also be treated.

Anti-Seize
Permits eliminating the seize problem typical of titanium alloys.

Technical specifications

Composition and applicable standards

Composition
The OX-Ti treatment transforms the surface of the titanium alloy into a compact layer of titanium oxide. The composition largely depends on the initial alloy.
Layer colour is obtained by self-colouring. No pigments or inks are used.

RoHS Conformity
RoHS conform. No restricted-use substances beyond maximum tolerated concentrations.

REACh Conformity
REACh conform. No SVHC in quantities greater than 0.1% by weight.

Tribological properties

Wear resistance
High colour durability thanks to the resistance to light wear and scratching of the titanium oxide layer.

Chemical properties

Chemical resistance
Excellent chemical resistance, typical of titanium alloys.
Chemical compatibility
Approximate values of compatibility with the coating environment. The actual resistance to the environment must in any case be tested in the field.
Hydrocarbons (e.g. petrol, diesel fuel, mineral oil, toluene)
Alcohols, ketones (e.g. ethanol, methanol, acetone)
Neutral saline solutions (e.g. sodium chloride, magnesium chloride, brine)
Halogenidric and reducing agents (e.g. sulphuric acid, hydrochloric acid, oxalic acid)
Oxidizing acids (e.g. nitric acid)
Diluted bases (e.g. diluted sodium hydroxide)
Oxidizing bases (e.g. sodium hypochlorite)
Concentrated bases (e.g. concentrated sodium hydroxide)
