TEST BENCH FOR WEAR OR LAPPING TESTING OF ENGINE PART COATINGS Russian patent published in 2009 - IPC G01N3/56 

FIELD: physics, tests.

SUBSTANCE: invention is related to the field of high-speed and high-temperature bench wear and lapping tests of engine part coatings. Test bench comprises rotation drive, imitator of disk with blades, imitator of shell, force controller, gas burner, force sensor, temperature sensor, sensor of engine drive rpm, motion sensor and I&C equipment with program control. Imitator of shell is made in the form of ring with the possibility of rotation, imitator of disk with blades is arranged in the form of immovable imitator of centrifugal force with indenter, besides indenter has at least one protrusion of arched shape, arranged as identical to comb of blade binding shelf, contacting with internal surface of ring and with radius equal to internal radius of ring. Length of indenter protrusion arc is equal to the length of blade binding shelf comb.

EFFECT: simplified design, expansion of technological resources.
