Cavitation damage to hydraulic structures is a recurring problem for utilities.  Serious damage can occur to components such as turbine runners, concrete spillways and draft tubes costing utilities thousands of dollars for repair and downtime.

Metallic Materials Protection

Powertech has the experience and facilities to evaluate formability, cavitation resistance, machinability, strength, weldability and cost when selecting materials for hydraulic equipment.  Through testing Powertech has been able to identify overlays and cladding materials, which will provide optimum protection against cavitation erosion.
