The anti-tufftride for ferrous materials was examined by applying inorganic coating on ferrous specimens. The coating was hardened at 150°C for 60 minutes. The coated specimens were water-cooled after soaking in the salt bath for 90 minutes, and tempered. Their microstructures were investigated.
The experimental results showed that the formations of compounds and the diffusion layer in the anti-tufftride zone of the specimen were very much restrained by the inorganic coating, and hardness increased very little. The inorganic coating was found to be very effective as anti-tufftride.
