Abstract
Fire protection sprinkler assemblies and methods of use in corrosive environments. The sprinkler assemblies include a corrosion resistant sprinkler frame made of a gradient material. The gradient material includes a polymeric layer interlocked about a corrosion-prone core in order to protect the frame structure from a corrosive environment. The interlock between the core and the protective polymer layers are defined by ionic bonding between the core and the outer polymer layer.
