This article deals with application of ultra-jet diagnosis of materials, which is one of the most promising and complex methods allowing one to estimate durability of materials instantly under various conditions. A review of existent mathematical models which allow one to evaluate the depth of a honeycomb originated on the surface of a material as a result of ultra-jet influence. Requirements to the ultra-jet interaction model and the material being diagnosed were determined. On the basis of these requirements a model which could be used in the technique of the ultra-jet instant diagnosis was proposed.
