PMET 73-20-7 is a tungsten carbide – chromium- nickel powder specifically designed for HVOF systems. It produces a hard, abrasive and corrosion resistant coating, with a service environment up to 1400° F (760° C). High chrome like finishes can be obtained by typical grinding or lapping techniques. PMET 73-20-7 is ideal for use in a wide variety of erosive and abrasive wear applications and corrosive environments. It should be used where added corrosion protection is required versus WC-Co coatings.
Applications:
- Oilfield Applications
- Chemical Processing Equipment
- Extrusion Screws
- Other Erosion and Abrasion Wear Applications
