POSITIVE COATING

ON THE CUTTING EDGE OF TECHNOLOGY

SPECIALIST IN THIN-LAYER VACUUM DEPOSITION

WHAT IS THIN-LAYER DEPOSITION?

Thin-layer deposition refers to a set of techniques used to deposit a thin layer or film of material on a substrate, or on previously deposited layers. The term “thin” is relative, but most deposition techniques can apply layers from around one micron to a few nanometres thick.

Vacuum treatment consists in treating the parts in a pre-evacuated sealed chamber.

Deposition techniques can be broken down into different categories:

WET

Galvanic treatment

Eloxide treatment

Anodisation treatment

DRY (vacuum)

CVD => ALD

ALD

CHEMICAL / PHYSICAL / ATOMIC

KNOW-HOW & EXPERTISE

Using the properties of PVD and ALD surface treatments in fields as diverse as watchmaking, jewellery, writing implements, etc., POSITIVE COATING has been able to develop combinations of these two technologies to push the envelope ever further.

The expertise developed in surface treatments for our customers with extremely high quality requirements has enabled us to identify various surface treatments with useful applications applicable to other fields.

The PVD and ALD treatments offered by POSITIVE COATING can be combined:

  • colouring / coding
  • encapsulation / biocompatibility
  • conductive or insulating electric properties
  • resistance to mechanical friction

Lucien Steinmann, the son of the company’s founder, joined the business in 2011 with a Masters in Biomedical Engineering under his belt. He detects and explores latent, unexploited needs for treatments in the medical field in particular.
