High Carbon Iron Based Wire proporties (Metco 8222)

[Met.Eng.]

Hi members,

We are planing to spray Metco 8222 for hard crome alternative and buld up coatings.
Is any body spray this wire with electric arc spray system? I am pleased if you answer these questios soon.

1-What is the max thicknesses ?
2-What is the boanding proporties?
3-Can we apply this wire without bond coat? (With grit blasting and maybe do other surface preparation steps)
4-What is the max hardnesses about this wire?

Best regards Good days

Hi Metallurgy_eng

1. I think probably in excess of 2mm

2/3. Not sure on value, but we sprayed without bond coat onto well prepared substrates with no problems.

4 If I remember correctly (it was nearly 15 years ago) it was very hard 1000+ HV/0.3.

Hmm ı check the bulltein the max thichness is 5 mm, the bond is 9500 mpa and telling self bonding proporties. The hardness is 48-50.

But thank you ur helping.

Good daysss
