CVD Titanium Nitride vs Multilayer CVD Tool Coating
CVD Titanium Nitride and Multilayer CVD Tool Coating are both cvd coatings finishes; multilayer CVD resists corrosion better.
CVD Titanium Nitride
CVD coatings · $$$$ · instant quote
CVD TiN is a thick, conformal gold tool coating used mainly on cemented-carbide inserts.
Multilayer CVD Tool Coating
CVD coatings · $$$$ · instant quote
Multilayer CVD combines TiN, TiCN, alumina, or related layers to balance adhesion, abrasion resistance, heat shielding, and wear indication on carbide inserts.
When to choose which
Choose CVD TiN
CVD TiN is the pick when its strengths below matter more than Multilayer CVD's.
- Conformal 5–15 µm coverage
- Strong adhesion
- About 2000–2500 HV hardness
Choose Multilayer CVD
Choose Multilayer CVD when maximum insert life needs multiple layers.
- Multiple wear mechanisms addressed in one stack
- 5–20 µm total thickness
- High hot-cutting durability
What the numbers say
- Multilayer CVD resists corrosion better.
- CVD TiN is the lower-cost option ($$$$).
- CVD TiN is conductive; Multilayer CVD is semi-conductive.
- Multilayer CVD tolerates more heat (1,000 °C continuous).
Scores side by side
Each score is 0–100 against every finish in this catalog. Corrosion is derived from salt-spray test duration and surface hardness from the finish layer's Vickers hardness where a measured figure exists; a finish that leaves the base metal's own surface is not rated for hardness. Cosmetic, lubricity and cost are FabDigit's engineering assessment. Scores and typical figures are screening data, not matched side-by-side tests or service-life rankings; ASTM B117 is a controlled salt-fog method, not a field-life prediction.
| Score | CVD TiN | Multilayer CVD |

| Cosmetic quality | 70 Very good | 45 Fair |
| Lubricity | 45 Fair | 48 Fair |
| Cost | 88 $$$$ | 98 $$$$ |
