DEVICE TO RECORD PROFILES OF SPEED OF FREE SURFACE OF SAMPLES UNDER HIGHER TEMPERATURES Russian patent published in 2013 - IPC G01N3/313 B01J3/08 

FIELD: testing equipment.

SUBSTANCE: device comprises a base, on which there is a flat-shaped sample 2 of a material, a striker 3 to form an impact wave in the sample 2 in the form of an aluminium disc, which is installed at the distance above the base with the sample, a generator 5 of a flat impact wave to speed up the striker 3, comprising an explosive charge with a paraffin insert, initiated from a detonator, at the same time the device is equipped with a heater 7 with smooth adjustment of spiral heating temperature, enclosed into a ceramic vessel, and which via a metal plate 8 is pressed to the surface of the sample 2, and a thermocouple 9, located between them. The ceramic body of the heater 7 is made with a central hole for passage of a probing beam 10 of a laser in an interferometric speed meter.

EFFECT: expansion of functional capabilities and increased validity of produced comparative results as a result of performance of serial sample testing under high temperatures.
