METHOD FOR TESTING HIGH-TEMPERATURE GAS CORROSION, ABRASIVE AND TEMPERATURE RESISTANCE OF MATERIALS AND COATINGS OF GAS TURBINE ENGINES UNDER MECHANICAL LOAD IN HIGH-SPEED GAS FLOWS Russian patent published in 2023 - IPC G01N17/00 

FIELD: material testing.

SUBSTANCE: invention relates to a method for testing high-temperature gas corrosion, abrasive and temperature resistance of materials and coatings of gas turbine engines under mechanical load in high-speed gas flows and can be used in mechanical engineering, aviation and aerospace industries. The method includes placing the test samples in a flame, supplying and controlling the flow of combustible gas in the reactor, supplying and regulating the air flow to cool the samples from the outside, introducing abrasive particles mixed with a salt solution into the fuel combustion flame, cyclic input and output of the test samples into the flame and a cooling zone. Additionally, the samples are connected at one end to the load cell, and the other end is connected to the lever of the frame of the mechanical loading module, which is connected through a hinge to the pneumatic cylinder, whereas the frame of the mechanical loading module with the pneumatic cylinder, samples, and the load cell moves along the rails perpendicular to the flame flow with the help of a drive from the heating zone into the cooling zone; during the heating-cooling cycles in an atmosphere of combustible corrosive gases, the test samples are subjected to mechanical tension.

EFFECT: testing high-temperature gas corrosion, abrasive and temperature resistance of samples of materials and alloys of turbojet engines in high-speed gas flows with cyclic input and output of the test samples into the flame and the cooling zone under static and dynamic mechanical loads, under conditions simulating the real working conditions of parts of turbojet engines.
