Enhanced mechanical seals performance by surface texturing and diamond coating

This article provides details of an experimental study that was carried out to analyse the intrinsic and combined effects of applying surface texturing and a diamond coating to mechanical seals. It explains how these methods enhance seal performance – especially under extreme operating conditions. In order to achieve this, the work involved experimentally comparing, in terms of friction torque and the leakage rate, the performance of textured mechanical seals, and textured and diamond-coated faces, with corresponding components that were untreated.
