Abstract
The corrosion resistance of composite materials in distilled water, which corresponds to the conditions of a humid environment, was studied. The conducted X-ray analysis of composite materials (Cu‒Y‒Zr)‒Mo showed that corrosion damage is observed in areas with structural defects. It was established that the oxidation process becomes more intense with increasing molybdenum concentration in the condensates.
