HVOF vs PTA

Mechanical thermal-spray coating versus metallurgically bonded hardfacing — when each process fits.

HVOF

Low substrate heat input, dense sprayed layers and precision grinding make HVOF ideal for many shaft, roll, hydraulic and erosion applications.

PTA

Thick metallurgically bonded overlays and geometry rebuilding make PTA highly effective for heavy wear and hardfacing.

Selection

HVOF and PTA are complementary; they are not interchangeable technologies.
