Conduct a 168 hour salt spray test according to GB/T1771-1991;
Clean the blade and floating rust on the blade after salt spray test with a wool brush dipped in 5% acetic acid solution, rinse thoroughly with clean water, and finally rinse with deionized water and quickly dry with a hair dryer. Immediately observe the corrosion and foaming morphology of the blade under a 50x microscope and record it.
