Coating with high hardness and low friction
The TiCN coating is an evolution of TiN: Carbon is used as interstitial element in the TiN grid; this tensions the coating, highly increasing its hardness, but also its fragility.
The TiCN coating produced by miniToolsCoating is characterized by a particular graduation of the Carbon percentage in the layer, designed to offer a good toughness while preserving the peculiar hardness of this coating.
The presence of Carbon allows a reduction of the coefficient of friction, reduces the chemical affinity of the coating to non-ferrous materials and increases resistance to corrosion.
The presence of Carbon allows to effectively use TiCN until the operating temperature reaches 350°C, even at a local level.
Technical features of the coating
| Coating colour | Hardness | Elastic modulus E | Oxidation temp. | Coeff. of friction on 100Cr6 | Deposition temp. | Typical thickness |
|---|---|---|---|---|---|---|
| Blue grey | 3200 ± 50 HV | 310 ± 10 GPa | 420°C | 0,30 | 450°C | 1-3 μm |
When to use the TiCN coating
HSS tools for drilling, tapping and milling, particularly for the machining of non-ferrous materials, such as aluminium or bronze, and light alloys.
Suitable in general for the shearing and forming of ferrous and non-ferrous materials, stainless steel and metal sheets that are treated galvanically, such as aluminized, galvanized or pre-tinned metal sheets.
Its particularly thin structure and low coefficient of friction allow excellent results in the moulding of plastic loaded with carbon or glass fibres.
