Summarize: 1. Before processing, it is necessary to detect the hardness of the body, stretch the test rod, and confirm that it is qualified before processing 2. Castings are tested for Brinell hardness according to ISO 6506-1, and the control range is above 85HB 3. The castings have been inspected by radiographs and conform to the third-level standard of ISO10049 4. The thickness of the coating must be 80-100 microns 5. Castings are subjected to salt spray test for 24 hours according to is09227 / astm b117, to ensure that no red rust is observed at the end of the salt spray test, once for each batch The spray masking tool needs to be re-customized
