Effect of graphite particles
Effect of graphite particles
(OP)
Hello,
What is the effect of graphite particles (coming out of machined cast iron) on the gear box life.
Please note that we do hot alkali wash the cast iron part before assembly. However, the black color is still seen on some places on the surface.
We need to use tissue paper and manually clear those spots.
I am wondering whether we really need to do the manual cleaning operation.
Your opinion please

Valuable advice from a professor many years ago: First, design for graceful failure. Everything we build will eventually fail, so we must strive to avoid injuries or secondary damage when that failure occurs. Only then can practicality and economics be properly considered.

RE: Effect of graphite particles
Depending upon what type of cast iron you are referring to, the graphite residue may or may not be detrimental. With grey iron, the graphite is in the form of flakes and is not really abrasive in nature. With ductile iron, the graphite is in the form of nodules, and these nodules are very abrasive due to an outer layer of silicon carbide that can form over each nodule during casting.
Hope that helps.
