INCREASING CORROSION RESISTANCE AND ABRASIVE RESISTANCE OF METAL STRUCTURES BASED ON AZOTING TECHNOLOGY IN LIQUID AND GASEOUS ENVIRONMENTS

Abstract

The article discusses one of the most effective methods of protection against high-temperature oxidation in gaseous and liquid environments - heat-resistant alloying. Today, our republic is conducting huge excavations in the field of mining metallurgy, and at the same time the largest and most expensive machines in the world are used there, the aggressiveness of salts used in azoting in a liquid medium and the importance of their neutralization, the complexity of controlling the composition of baths and other issues of the need to develop azoting methods in a competitive gas environment are considered. The issues of carrying out the process of gas azoting in atmospheric conditions with partially dissociated ammonia, ammonia diluted with nitrogen, air, hydrogen, carbon-containing gases (methane, propane, endogas, etc.) and setting the flow rate of ammonia, setting the degree of dissociation by regulating the flow rate of ammonia are studied.
