Abstract

The invention discloses a composite material with high corrosion resistance. The composite material is prepared from the following raw materials in parts by weight: 5-15 parts of La2O3, 5-15 parts ofAl2O3, 70-90 parts of PbF2, 15-25 parts of PbO and 15-25 parts of H3BO3. According to the invention, the LaAl11O18 corrosion-resistant composite material is synthesized by sintering La2O3 and Al2O3 used as main materials and PbF2, PbO and H3BO3 used as auxiliary materials in an aluminum oxide crucible. The raw materials are stirred and mixed and then subjected to microwave radiation treatment, sothat the activity of the raw materials is improved. Then, the raw materials are more easily combined with one another after ion beam bombardment treatment.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a highly corrosion-resistant composite material and a preparation method thereof. Background technique [0002] Corrosion resistance is the ability of metal materials to resist the corrosion damage of the surrounding medium, which is called corrosion resistance. Determined by the composition, chemical properties, and structure of the material, corrosion is generally divided into chemical corrosion, electrochemical corrosion, general corrosion, and intergranular corrosion. Chemical corrosion is the result of the direct chemical interaction between the metal and the surrounding medium. It includes gas corrosion and metal corrosion. There are two forms of corrosion in non-electrolyte, which are characterized by the fact that no current is generated during the corrosion process, and the corrosion products are deposited on the metal surface; electrochemical corrosion is th...
