Regarding the problem of sulfur concentration in silver corrosion!
Thread Content
This is a document by Dr. Liu Lin on the corrosion of silver sheets. I have two doubts. One is that the sulfur concentration listed in this document is quite different from that given in another document. Second, there is another one at the back: when qualified oil is mixed with 12% grade oil, the result is grade one, but according to the calculation, the sulfur concentration should be grade zero. Why is this? Friends please answer!
Silver flake corrosion (including copper flake corrosion) is a comprehensive effect of total active sulfur and other active substances. Elemental sulfur is only one type of active sulfur. Changes in active substances make it difficult for the corrosion grade to have a linear relationship with elemental sulfur.
But generally speaking, the corrosion level is still proportional to the sulfur concentration.
