Silicon Nitride Ceramic:

Silicon nitride is an extremely thin, strong, dense and stable chromium-rich oxide film (protective film) formed on its surface. Prevent oxygen atoms from continuing to infiltrate and continue to oxidize, and gain resistance to rust. Once there is a certain reason, this kind of film is continuously destroyed, the oxygen atoms in the air or liquid will continuously separate out, forming loose iron oxide, and the metal surface will be continuously rusted.
Due to cost considerations, many domestic manufacturers have reduced chromium and nickel in stainless steel, and increased the content of manganese. Experts believe that the reason why stainless steel can be rust-free is because of the presence of chromium and nickel. Lowering the content of these two components will reduce the rust-proof performance.
Matters needing attention in the machining of silicon nitride ceramics:
Processing area: The processing area of stainless steel parts should be relatively fixed. The platform of the processing area should take protective measures, such as laying rubber mats. When processing stainless steel parts, damage to the protective layer on the surface of the stainless steel parts should be avoided. Chloride ions are widespread, such as salt/sweat traces/sea water/sea breeze/soil and so on. Stainless steel corrodes quickly in the presence of chloride ions, even exceeding that of ordinary low-carbon steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry. (In this way, you can give him an "improper use".) There is an example in the United States: a company used an oak container to hold a solution containing chloride ions. The container has been used for nearly a hundred years, and it was planned to be replaced in the 1990s. Because the oak material is not modern enough, the container leaked due to corrosion 16 days after the replacement with silicon nitride parts. The alloy elements have not been dissolved into the matrix without solid solution treatment, resulting in low alloy content of the matrix structure and poor corrosion resistance.
