Lige et lille spørgsmål til

[MortenKN]

Er der nogen der har erfaringer med de såkaldte PVD coatede ure som f.eks Bell & Ross Instrument eller U-Boat? Syntes det er kanon elegant, men tvivler lidt på holdbarheden. Hvad siger kenderne? Holder det og kræver det at man skvatter på cykel før man banker belægningen af?

Prøv søgefunktionen og søg på PVD. Den er ikke så holdbar. Derimod er ceramic og DLC langt stærkere.

Al coating går af med tiden. Det skal man vide. DLC er dog den hårdeste indtil videre såvidt jeg ved.

..det er ikke helt rigtigt. DLC er sikkert den stærkeste hvis man vil have en sort. Kan man klare sig med en anden farve - fx lysebrun er TiAlN meget stærkere. Det bruges fx til at forstærke stårbor men Urwerk kom med en model her i år hvor det er blæst på en 103ér - her er lidt jeg har saxet fra Ian Skeller:

"TAIlN is a an industrial coating used to improve the characteristics on steel in machine tools (tools like the image above).

Steel is harder than gold, nearly twice as hard:

Gold: 380 Vickers
Steel: 600 Vickers
Temperature hardened steel: 800 Vickers
PVD coat: 1800 Vickers
PE-CVD coat. 2200 Vickers
Tiain coat: 3500 Vickers
Sapphire (crystal): 4000 Vickers
Diamond: 6000 Vickers

As with any steel (or gold or platinum) case, the metal can be deformed by dents or scratches. The TAIlN coating is extremely thin - but twice the thickness of PVD - and bonds very strongly to the steel underneath. If you knock the case against a hard surface then it is likely to dent (just like any steel case).

Because the TAIlN bonds strongly to the steel it does not chip off as easily as PVD, so you may end up with a deformed/dented case with the TAIlN surface intact. Like the dent in a car panel that does not scratch the paint.

Gold is much softer than steel and will deform much easier. If you use the term dent instead of deform then it may make things clearer. Any metal will deform (or chip) if knocked hard enough - it has nothing to do with being steel.

My understanding is that some SINN models have a specially hardened steel and if that is the case then it will be harder to deform/scratch/dent that case then steel of the 103.08. The reason for URWERK not using a super hardened steel is that it could not be polished to the glossy fine sheen that URWERK feels adds a special lustre to the surface of the 103.08.

The 103.08 is designed to be a knock about beater. TAIlN makes the steel more scratch resistant but does not make it scratch proof"
