Welcome To AMC's homepage for PVD Coatings
What is PVD? Simply this can be defined as Physical Vapor Deposition and can encompass various technologies such as CAPVD (Cathodic Arc Physical Vapor Deposition), Sputter Ion Plating, and EBPVD (Electron Beam Physical Vapor Deposition.)
Tooling Applications
Where has PVD found its principle applications? It works very well in low and moderate temperature applications - for coating cutting tools - such as high speed steel drills, hobbs, saw blades, dental tools, etc. (This technique has displaced CVD for coating of non-tungsten carbide cobalt cutting tools because CVD requires a temperature typically greater than 700 deg. C - and more typically in the 980 - 1038 deg. C. Range.
 Sidrabe's PVD System Example
This system can be configured as either a CAPVD or SIP system.

Aerospace Applications
Typical aerospace uses have ben in the area of TBC's (Thermal Barrier Coatings) - films that are typically yttria stabilized zirconia - and are as much as 10 mills thick (250 microns). In addition, erosion resistant coatings such as TiN, TiAlN, ZrN etc have been used on compressor components typically made out of titanium-aluminum alloys, steels and nickel based superalloys.

Decorative Coatings
PVD Coatings of TiN (Titanium Nitride) and ZrN (Zirconium Nitride) when deposited in the 1 - 5 micron range have a "golden" appearance.

Decorative Coatings
Sidrabe of Riga, Latvia has designed equipment for the decorative market-place coating Church Icons as seen in the above photographs.
