Case History #023 REV.04-97

Cast hydro wheel attacked by erosion corrosion and cavitation.

After abrasive blasting, unit was coated with three layers of Arcor™S-16. Arcor™ TS-RB was installed between the first and second coat in areas where pitting was severe.

This coating system not only protects unit from further attack, but also makes the runner more efficient. This runner was coated in September of 1989. To date it is still in service.

Abrasive-blasting to white metal SSPC-5.

Primed and rebuilt with ARCOR S-16/TS-RB.

Intermediate and top-coat ARCOR S-16.
