Technical Field

The invention belongs to the field of metal alloys, and relates to a high-temperature-resistant corrosion-resistant dissolvable fracturing material.

According to the design, the metal nickel is electroplated on the soluble magnesium-based alloy for coating, so that the magnesium-based alloy can be insoluble in the early stage under high temperature and high pressure and can be quickly dissolved in the later stage, and the requirement of fracturing construction on insolubility of the soluble material in the early stage is met.
