Thermal Spraying of Fan Impeller Blades
The induced-draft fan is one of the boiler’s primary auxiliary devices, responsible for continuously conveying gases. The main failure mode of the induced-draft fan is erosive wear caused by solid particles in the flue gas impacting and eroding its blades. Failure of the fan blades can lead to reduced operational efficiency or even complete shutdown.

Fan impeller wear repair
The induced-draft fan is one of the boiler’s key auxiliary devices, responsible for continuously conveying gases. The primary failure mode of induced-draft fans is erosive wear caused by solid particles in the flue gas impacting and eroding the fan blades. Failure of the fan blades can lead to reduced operational efficiency or even complete shutdown. In today’s world, where energy resources are receiving increasing attention, research into the erosion resistance of induced-draft fan blades has become ever more critical.
Arc spraying technology has the following advantages:
1. Excellent coating performance: By employing arc spraying technology, it is possible to obtain coatings with high surface performance and bonding strength without preheating or using expensive substrate materials.
2. High spraying efficiency: When the spraying current is 300A, the zinc-spraying efficiency can reach 39 kg/h, and the aluminum-spraying efficiency can reach 10 kg/h.
3. High energy utilization rate (high energy efficiency): The energy utilization rate of arc spraying can reach as high as 57%, whereas the energy utilization rates for plasma spraying and flame spraying are only around 12%!
The coating prepared by our company possesses the following properties:
The SX-801 coating exhibits extraordinary mechanical and physical properties:
1. The coating hardness HV0.3 is 1015 (equivalent to HRC70).
2. Coating adhesion strength: 60.5 MPa
3. Coating porosity: <1%
4. The coating’s erosion and wear resistance reaches the level of HVOF-sprayed NiCr-Cr3C2 coatings, while its resistance to abrasive particle wear is...
The wear rate is twice that of the HVOF-sprayed NiCr-Cr3C2 coating.
5. High-temperature resistance: When the erosion angle is 25°, its erosion resistance will not decrease even at temperatures as high as 1000°C. However, when the erosion angle is 90°, its erosion resistance begins to decline only above 800°C.
Prev: Non-standard custom-made various wear-resistant mechanical seals and chemical pump shaft sleeves.
