Wear Erosion Coating
Erosive wear occurs when hard particles present in the flowing media strike the surface of the component, causing the removal of material. The severity of wear is dependent on the hardness of the particle, its velocity and angle of impact. Erosive wear usually occurs in applications such as Oil & Gas, Pumps & Valves, Power Generation etc.
Solution
Hard material deposited through the HP-HVOF process having good adhesion with the base material will provide good resistance to low-angle particulate attack. For high-angle particulate attack, a metallurgically bonded material deposited by PTAW or Spray and Fuse process is preferred. Erosion resistant coatings combat wear caused by abrasive particles and protect surfaces from such damage. Few coatings suggested by us for applications involving Erosive Wear are:
| Material Category | Material Code |
|---|---|
| Alloys & Metal Blend | - C52 - C83X - C85 - C92 |
| Carbide | - DC08 - DC09 |
