Coating's Microstructures 6

1st Generation CT=1.84µm

2nd Generation

Monoblock Structure Without Adhesion Layer The monoblock structure without adhesion layer can be produced by the fastest, most economical process. All targets are made of the same material and run during the whole deposition process.

Conventional Structures With Adhesion Layer

Monoblock

Gradient (G)

Multilayer (ML) Period > 20 nm

CT=1.92µm

CT=2.5µm

CT=2.52µm

In gradient structures the ratio of hard components (e.g. cubic AlN) is continuously increased to obtain 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.

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

3rd Generation: TripleCoatings3®

Nanocomposite (NC)

Nanolayer (NL) Period < 20 nm

5 nm

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

4th Generation:

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

The "parent" coatings determine the application fields of all "children" coatings in the same row. The "children" coatings specify PLATIT's standard coatings, which can be deposited by the machine of the columns. The exponent x (coatingx) describes the generation of the coating.
