Ionbond™ 22 AITiCrN

Versatile PVD coating for use in metal forming, die casting and plastic injection molding applications

Ionbond 22 is an AlTiCrN coating that possesses excellent toughness, wear resistance, and galling resistance. This combination of properties makes Ionbond 22 a good coating candidate for light to medium forming applications, including those involving carbon steels, austenitic stainless steels, galvanized, prepainted or coated steels, and copper alloys. The ability to combine Ionbond 22 with nitriding expands its successful application to include higher strength materials such as ferritic stainless steels, high strength low alloy steels (HSLA), and advanced high strength steel (AHSS) applications.

Furthermore, Ionbond 22 has an excellent thermal stability and corrosion resistance, which, when combined with nitriding, enables it to be used in high temperature forming applications such as die casting, hot extrusion, hot stamping, and hot forging. For aluminum die casting applications, Ionbond 22 is particularly effective in reducing both the erosive wear and the sticking of aluminum that are so prevalent in these applications. Deposition as a duplex coating by combining Ionbond 22 with nitriding of the tool material will significantly improve the tool performance.

Ionbond 22 is generally deposited between 450-550 °C. These processing temperatures require tool materials to be tempered at higher temperatures in order to avoid softening or dimensional changes.
