3. Generation:

Especially at high aluminum content the monoblock coating should be started with adhesion layer (e.g. TiN or CrN).

At gradient structure the ratio of hard components (e.g. cubic AlN) will be continuously increased obtaining the highest hardness on the top of the coating.

Multilayer structures have higher toughness at lower hardness than comparable monoblock coatings. The "sandwich" structure absorbs the cracks by the sublayers.

Nanolayer is the conventional structure for the so called Nanocoatings. It is a finer version of multilayers with a period of < 20 nm.

At depositing Nanocomposites the hard nanocrystalline grains (TiAlN or AlCrN) become embedded in an amorphous SiN-Matrix.

Monoblock Structure Without Adhesion Layer

Conventional Structures With Adhesion Layer

The monoblock structure without adhesion layer can be produced by the fastest, most economical process. All targets are the same and run during the whole deposition process.
