The present invention relates to a wear resistant coating suitable to be deposited on cutting tool inserts for chip forming metal machining. The coating comprises at least two layers with different grain size, but with essentially the same composition. The coating is deposited by physical vapour ...
PVD coating technology is an environmentally friendly surface treatment method that can truly obtain micron coatings without pollution. It can prepare various single metal films (such as aluminum, titanium, zirconium, chromium, etc.), nitride films (tin, ZrN, CrN, TiAlN), carbide films (TIC, TiC...
About PVD Coating About PVD Coating Physical Vapor Deposition (PVD) is a process to produce a metal vapor that can be deposited on electrically conductive materials as a thin highly adhered pure metal or alloy coating. The process is carried out in a vacuum chamber at high vacuum (10-6 torr...

PVD coatings on metal forming tools may enormously reduce tool and workpiece wear in cold forging or deliver special functions even in the absence of lubricants. However, the abdication of lubricants goes along with the requirement that the dry tribological system has to withstand the increased ...
Therefore, a CVD device for coating ceramic particles was constructed and is described in this paper. Furthermore, coatings deposited on the ceramic sub-strates were investigated by means of RBS, SEM and XRD. In addition, the feasibility of producing metal matrix composites (MMC) by admixing ...
In sputtering, vapor is created when a metal target is bombarded with energetic gas ions. The cathodic arc method, on the other hand, utilizes repeated vacuum arc discharges to strike the metal target and evaporate the material. Frequently asked questions on PVD coating services What are the ...
As the process transfers the coating material as a single atom or on the molecular level, it can provide extremely pure and high performance coatings which for many applications can be preferable to other methods used. At the heart of every microchip, and semiconductor device, durable protective ...
Physical Vapor Deposition PVD coating refers to a variety of environmental friendly vacuum deposition processes for producing metal-based hard coatings by means of generation of partially ionized metal vapor, its reaction with certain gases and by forming a thin film with a specified composition on th...
