摘要： An improved glass or silicon ink jet nozzle is described having a three-layer coating that provides improved mechanical and chemical properties. The coating includes a first layer of silicon nitride, an intermediate layer graded in composition, and a top-most layer of aluminum nitride. The intermediate layer is typically a solid solution of silicon and aluminum nitrides being silicon-rich at the interface with the silicon nitride layer, and aluminum-rich at the interface with the overlying aluminum nitride layer. This three-layer coating provides the required dielectric properties, displays very low wettability, and is extremely corrosion resistant to all types of inks.
