Jul 25, 2019 · Also, the same coating may not be used on all parts of the same valve, adds Thomas Schmidt, product manager, Europe, Flowserve. With inner valve parts, for example, "the throughput of the valve might be coated in chrome carbide or tungsten carbide and the seat and ball will be a different material," he explains. Type of Coatings
Grinding Balls. Larger and more resilient samples can be homogenized through the use of grinding balls. In contrast to grinding beads, which are a pool of beads within a given size range, grinding balls are spherical and precision ground to a specific diameter. They are made of stainless steel, tungsten carbide, or zirconium oxide.
