Ionbond™ 35

PVD Coating for use in aluminum die casting, hot stamping, and plastic injection molding applications

Ionbond™ 35 provides superior performance to PVD TiAlN and CrN coatings in aluminum die casting applications. Ionbond™ 35 exhibits excellent resistance to penetration by molten aluminum, high abrasive wear resistance to the silicon common in die casting alloys, and superior thermal fatigue resistance. These properties lead to improved resistance to soldering (aluminum sticking) and erosion that are the common tool failure modes in aluminum die casting applications.

Its high thermal stability, resistance to aluminum corrosive attack and mechanical fatigue resistance make Ionbond™ 35 a superior candidte for aluminum extrusion, and hot stamping or press hardening applications, particularly those where the steel material is coated with an aluminum alloy. Further, the equiaxed grain structure of Ionbond™ 35 produces superior corrosion resistance allowing it to perform well in plastic molding applications utilizing resins that produce corrosive vapors during the process.

Ionbond™ 35 can be deposited over a wide range of temperatures. This versatile process allows a variety of tool materials to be successfully coated below the respective tempering temperature which ensures that no softening or dimensional changes will occur.
