Definition - What does Oxide Jacking mean?
Oxide jacking is the expansive rusting or rust burst that can lead to severe damage to structures that are made of ceramics, concrete, stone and other materials with reinforced metal parts.
It can be described as the displacement of elements due to steel products and iron expansion as metal undergoes rusting and turns to iron oxide. Corrosion of metals such as aluminum could also lead to oxide jacking.
Corrosionpedia explains Oxide Jacking
In oxide jacking, rust forms when oxygen and iron react with each other. This usually happens in the presence of an electrolyte like water. Thus, this is more likely to happen if moisture collects between the linings of industrial equipment and systems. Some of the factors that can influence rust jacking include:
- Replacement rate
- Duty cycle
- Quality of paint process
- Exposure to chemical compounds and seawater
According to experts in metallurgy, the process of oxidation is typically accompanied by net expansion. Hence, when this happens within a confined space, stresses are produced in the metal or surrounding environment like cement or stone. Too much energy is released through oxidation, making the generated stresses powerful enough to fracture or deform all types of materials.
Oxide jacking can be prevented through the implementation of certain measures like the application of anticorrosion paint that offers the best level of oxidation protection. Typically, the surfaces and materials are dipped or sprayed with paint to promote higher durability and better adhesion.
Without adequate protection or coating, the bare material is exposed to various conditions such as grime and spray. Such situations can trigger oxidation, that later leads to rust formation that could creep in and cause components to break and fracture.
