Hardfacing Spray Powders
There are 2 basic types of powder:-
- Base powders with a hardness scale of 20 – 60 Hrc.
- Ready mixed powders with cast tungsten carbide particles 40 - 80µ to give increased wear resistance.
- These are atomised Nickel alloy powders containing Nickel, Chromium, Boron, and Silicon.
- Boron and Silicon are good fixing elements.
- Hardness values are dependent upon the Chromium-Boron-Silicon content.
Flexible Electrode – Hardfacing Cord
- Central metal core : 1.2mm diameter Nickel wire.
- Matrix : Nickel based powder - hardness value 40Hrc (content 35%).
- Cast or Spherical tungsten carbide particles – with grains of varying shapes and sizes – hardness value 2000 – 3000HV (content 65%)
Again there are 2 basic types:
- Tenrock 2000 – Cord containing cast tungsten carbide : Good for wear resistance.
- Tenrock 3000 – Cord containing spherical tungsten carbide : Increased shock / impact resistance.
- Dense homogeneous coating from 2 – 10mm thickness.
- High wear resistance.
- Good corrosion resistance.
- Average density 13.6 kg/dm3.
- Easily applied by any competent welder.
