Double acid
on titanium

Neutralises contamination risk and improves the osseointegration capability of objects with chemical pickling treatment and acid etching.

Benefit of double acid etching

  • 01.

    Reduction in risk of surfaces being contaminated with extraneous microparticles 

  • 02.

    Excellent osseointegration capability

Process of double acid etching

The technique of double acid etching on titanium involves creating macro roughness followed by etching with acid, which puts micro roughness over the prior macro roughness. 
The production cycles involve an initial phase with pretreatment, washing and rinsing the implants received, to ensure they are all equally clean, eliminating or minimising the presence of oils and grease coming from external mechanical processes.

After the initial wash, the first acid etching procedure is carried out on the implants. The part is then washed, which is followed by chemical pickling treatment and acid etching. Next step is the neutralisation process, washing and rinsing with water to eliminate chemical residue left behind by the pickling and etching process. After washing, the implants are dried and decontaminated with a plasma treatment.

Since 1996, Alticolor has been the trusted point of reference for companies in need of treatments on titanium components.

Alticolor treatments undergo rigorous control procedures
resulting in certification to guarantee the quality
of the process management.
