| Abstract: |
| N485 precision alloy is the optimal material to make CRT anode button at present. We focus on the oxidation performance of CRT anode button made of N485 sealing alloy at high temperature wet hydrogen. SEM and EDS techniques were used to analyse the microstructure and composition of anode buttons oxide film. The sealing and heat-resistant capability of oxidic film were studied with high-frequency sealing simulator. It is shown that the thickness of oxide film and the content of Cr203 will increase and the capability of sealing and heat-resistance will be improved when oxidizing temperature and time are mcreased at a certain extent. |
