EFFECT OF ULTRASOUND ON SCALE FORMATION AND CORROSION PROTECTION OF THE HEAT EXCHANGE SURFACE
The processes of scale formation and corrosion on the surface of heat exchange using ultrasound with a frequency of 26.5 kHz of low power in the provisional and transient modes and without it were studied. The functional dependences of the build-up of the specific mass of the scale and the corrosion rate are established, depending on the ultrasonic irradiation regimes. The morphology and structure of the scaled layers formed by the scanning electron microscopy method are studied. It has been established that ultrasonic treatment of low intensity promotes the formation and maintenance of a phase microlayer with anticorrosion properties, which practically does not reduce the heat exhange between the metal surface and the coolant.
