Seal and a method of manufacturing the seal

Abstract:

A method for manufacturing a seal is disclosed. The method includes depositing one or more layers of a first material on a metal base plate of a second material to form a main seal body of the seal. The second material is different from the first material. The method further includes separating the seal from the metal base plate such that the seal includes the main seal body and an outer seal layer retained on the main seal body to form a seal face surface of the seal. The outer seal layer is formed of a portion of the metal base plate.
