"ZTA particulate from CoC seems to have an adverse effect on metal components leading to increased corrosion."
Yeah this is a question I've had. If we know about galvanic corrosion of dissimilar metals, then is a ceramicized metal the equivalent of a dissimilar metal?
These studies are done on wear outside of the human body to determine the amount of wear particulate which negates the discrepancy of in vivo phase changes that lead to shattering and possibly increased wear particulate.
"What I can extrapolate from this is metals and CoC ZTA do not intermix well"
Another possibility other than ceramicized metals interacting with galvanic corrosion of dissimilar metals is simply adding grit into the synovial. If the synovial fluid is the oil lubricant in your car engine, the joint would be your main bearing. leftover particulate would be like pouring sand into your engines oil. You would see increased wear in the main bearing.
Therefore the bodies ability to eliminate the Silicon Nitride particulate would be another hidden benefit of the superiority of Silicon Nitride. Since it allows for the natural removal of the "sand in your oil" analogy.
