hi.
i have a 1:1 gearbox.
one teeth has erosion in surface and opposith teeth in other gear hasn't any erosion.what is the couse of erosion?
the depth of erosion is approximately 1mm.
there isn't any erosion in all other teeth.
Op
Need clearer picture
But appears to be pitting and could be corrosion.
Pitting is contact stress, and lubrication could have failed, or the surface of tooth profiles are not harden correctly.
Contact the gear box manufacture get them involved. The documentation of manufacturing , material and heat treat certifications need evaluation. Must not run this gear box, or catastrophic failure will occur.
Op verify if there was a etch and temper.
If temper etch was not properly neutralized it will corrode.
Or if not tempered correctly will cause hydrogen embrittlement
