Abstract:
A seal ring having a sealing surface (22) includes first and second portions (24, 26), and may be configured for mating with a mating ring. The first portion (24) may include a first surface roughness, the second portion (26) may include a second surface roughness, and the second surface roughness may be comparatively rougher than the first surface roughness. In embodiments, a seal assembly may include a seal ring including a first sealing surface (22), the sealing surface including first and second portions (24, 26); and a mating ring including a second sealing surface; wherein, the first portion (24) has a first surface roughness the second surface (26) includes a second surface roughness, and the second surface roughness being rougher than the first surface roughness.
