Abstract
Description
technical field
[0001] The invention is related to metal materials, and is a metal corrosion monitoring optical fiber grating sensor device for monitoring the corrosion status of metal structural materials. The monitoring of the occurrence of corrosion can also be used for the corrosion of structures of other metal materials in the ambient atmosphere. Background technique
[0002] Reinforced concrete and steel cables are the most widely used building structural materials in modern infrastructure. Steel has the advantages of high strength, easy processing, and abundant resources on the earth, but iron, the main component of steel, is easily oxidized and corroded by moisture and oxygen. Corrosion of steel cables and steel bars leads to a decrease in the strength of the structure, and even leads to the collapse of the structure, resulting in huge losses of human life and property. Aluminum and other metal materials are also widely used structural materials, such as aircraft a...
