摘要： A sample composed of a nickel-based metal is immersed in a corrosive solution (aqueous solution containing an acid and sodium chloride). The sample that has been immersed in the corrosive solution is exposed to a flame of engine oil, and further heated. By immersing the sample in the particular corrosive solution, a Ni-enriched phase which is deficient in additional elements and in which the Ni concentration increases is formed in a surface layer region of the sample. By exposing the sample having the Ni-enriched phase to the flame of the engine oil, components in the engine oil are activated and brought into contact with the sample to form a low-melting point phase in the surface layer region of the sample. By heating the sample having the low-melting point phase to melt the low-melting point phase and resolidifying the low-melting point phase, particles and the like can be formed depending on the type of material of the sample. The ease of the generation of particles can be evaluated by using simple equipment instead of an engine for testing.
