  • APPLICATION ON A WIDE RANGE OF MATERIALS
  • PROTECTION OF MEDICAL IMPLANTS FROM BODILY FLUIDS

ANTICORROSION TREATMENT

Perfectly suited to protecting copper alloys such as brass, nickel silver, as well as tungsten and aluminium, this treatment replaces galvanic undercoats for the protection of watch parts produced in these materials.

The protection provided is greater than that of a galvanically applied coating, despite the thickness being around 20 times less. So the thinness of this treatment means that parts receive a highly uniform and compliant coating, without altering their dimensions. So components can still be driven or mounted without any problems.

A TRANSPARENT PROTECTION

Depositing a well-defined, transparent, dense and impermeable thin layer provides excellent protection against tarnishing of silver and 4N and 5N gold alloys.

PROTECTIVE ENCAPSULATION

The encapsulation of medical implants, for example, ensures that the device is sealed against bodily fluids and prevents implant particles from escaping into the body. 

These encapsulation properties can also be improved by combining POSITIVE COATING coatings with other technologies, so as to create multi-layer treatments.



HIGH-RELIABILITY TREATMENT

The ultra-thin films provided by POSITIVE COATING are perfectly suited to encapsulation of highly corrosive materials, and miniaturised electronics which require a reliable protection method.

BIOCOMPATIBLE TREATMENT

These coatings are applicable to a wide range of materials, such as stainless steel, Nitinol, cobalt-chromium alloys, titanium alloys, ceramic, polymers, and many more.

This hermetic, leakproof envelope safeguards the patient from any release of toxic metal ions from the implant.
