Triplex-Q Made in Germany Carbide End mills
New line High Quality Carbide end mills offer efficient and productivity rate. When do you need hig speed productions is very important end mill life long plus quantities of cuts, titanium and silicon (TiSi) make an outstanding team for nitride hard material coatings. Silicon guarantees excellent resistance to oxidation while the presence of titanium ensures particularly hard coatings. When combined, the two elements are wear resistant even at very high temperatures. The invention relates to a super-hard nano-micron multilayer composite coating and a preparation method thereof. The super-hard nano-micron multilayer composite coating is composed of a TiAlSiN layer, a TiCN layer and a TiN layer. The coating structures are the TiN layer, the TiCN layer and the TiAlSiN layer from inside to outside sequentially. The preparation method of the coating is physical vapor deposition (PVD). All the layers of the coating structures are nano-micron composite structures. The TiAlSiN /TiCN /TiN multilayer coating prepared through the preparation method is of the thickness of 2.5 um-3.5 um and has high hardness, abrasion resistance and high-temperature oxidation resistance. Through a transition layer structure of the coating, not only is the binding force of the coating and a substrate improved, are the intrinsic stress and the thermal stress of growth of the coating reduced, but also the using performance and the service life of a tool and mould can be improved by a large margin. Compared with the prior art, the coating structures of the coating is deposited through cathode arc ion plating, and cathode arc ion plating has the characteristics of high ionization rate and round plating performance, low deposition temperature, and the like. Compared with other methods, the prepared coating has more outstanding performance.
TiSiN-coated tools are extremely wear-resistant and permit high machining speeds. Machining operations without the use of coolants also pose no problem. Even tough materials such as nickel-based alloys and titanium-based materials are easy to machine using titanium-silicon nitride-coated tools.
The titanium nitride crystals are embedded in an amorphous Si3N4 matrix and together form a ceramic nanocomposite coating. TiSiN layers are applied to the tool using the reactive magnetron sputtering or arc evaporation process.
