TiAlNpinnoitteet
TiAlNpinnoitteet, or Titanium Aluminum Nitride coatings, are a type of advanced thin film PVD (Physical Vapor Deposition) coating widely used in the metalworking industry. These coatings are known for their exceptional hardness, high temperature resistance, and excellent wear characteristics. The combination of titanium and aluminum within the nitride matrix creates a material that is significantly harder than traditional coatings like TiN (Titanium Nitride). Furthermore, TiAlN coatings form a protective aluminum oxide layer at elevated temperatures, which further enhances their performance in high-speed machining applications by reducing friction and preventing adhesion of workpiece material. This self-healing property is a key differentiator. The typical composition of TiAlN coatings can vary, but the ratio of titanium to aluminum is crucial for optimizing its properties. They are commonly applied to cutting tools, such as drills, end mills, and inserts, as well as wear parts and molds. The increased tool life and improved surface finish of machined parts are significant benefits of using TiAlNpinnoitteet. Their effectiveness is particularly pronounced when machining difficult-to-cut materials like stainless steels, titanium alloys, and nickel-based superalloys.
