Ceramic coating based on tantalum (Ta) for applications subjected to extremely corrosive environments

Objective

To obtain an extremely dense coating which withstands corrosive environments.

Results

Tantalum-based layer obtained through HIPIMS (High Power Impulse Magnetron Sputtering) technology.

Ceramic coating based on tantalum (Ta) for applications subjected to extremely corrosive environments

The tantalum-based coating benefits from the extraordinary anti-corrosive properties and chemical stability of tantalum which is virtually immune to attack by acids and liquid metals. It is also a biocompatible material.

The new HIPIMS (High Power Impulse Magnetron Sputtering) technology implemented in IK4-TEKNIKER, allows an extremely dense deposition of coatings and better adhesion to the substrate. This results in increased hardness and excellent corrosion resistance in comparison with coatings deposited using conventional sputtering technology.

This approach is applicable to:
