Abstract
A method for manufacturing a seal is disclosed. The method includes coating a sealing surface substrate of an annular main seal body of the seal with a layer of Molybdenum, and melting the layer of Molybdenum to fuse the layer of Molybdenum into the sealing surface substrate to form an alloyed outer seal layer. The alloyed outer seal layer forms a sealing surface of the seal.
