PROSPECTS FOR THE USE OF CATALYTIC COATINGS CONTAINING RARE EATH METALS IN HEAT RECOVERY DEVICES USED IN THE ENERGY SECTOR

The influence of the content of cerium oxide and neodymium oxide in the initial powder mixture on the properties of porous coatings obtained using the method of cold gas-dynamic spraying and subsequent annealing has been studied. It has been established that the introduction of rare-earth metal oxides up to 8% increases the specific surface area and resistance of coatings to ultrasonic vibrations.
