| titleOfInvention | Method for testing the porosity of metallographic specimens of abradable sealant coatings under an optical microscope |
| abstract | The invention discloses a method for testing the porosity of a metallographic sample of a wearable sealing coating under an optical microscope, comprising the following steps: preparing a mixture that can penetrate into the pores of the coating and solidifying; into the mold; pour the mixture into the sample preparation mold, so that the metallographic sample is immersed in the mixture; put the sample preparation mold containing the metallographic sample and the mixture into the oven to keep warm; take out the sample preparation mold from the oven and keep it at room temperature Place to make the mixture completely solidify; take out the metallographic sample from the sample preparation mold for grinding and polishing; place the ground and polished metallographic sample under an optical microscope for observation, take metallographic pictures, and determine the porosity. The present invention adopts the method of mixing liquid epoxy resin with plasticizer, cross-linking agent, modifier, diluent and color developer and then heating and infiltrating into the pores of the coating for curing, and the specific position and position of the pores can be observed under an optical microscope. area, calculate the porosity, and realize the determination of porosity under the conditions of conventional coating metallographic testing. |
