INCREASING THE CORROSION RESISTANCE OF WELDED JOINTS OF HEAT-RESISTANT NICKEL ALLOY WITH STEEL

For parts and assemblies of a turbopump unit (TPU) and a liquid rocket engine, welded joints of steel and heat-resistant alloys are used. Considering that the search for replacements by several materials at once, the study of their mutual compatibility in a product takes considerable time and money. Therefore, it would be better to replace it with one alloy, and the unification of the material used allowed the structure to work as a whole. After exploring various options, the substitutes for research were selected inconel 718.
