Definition - What does Inhibitor mean?
Inhibitors are substances that reduce the occurrence rate of a chemical reaction, such as corrosion. They may refer to corrosion inhibitors that aid the prolonging of material life due to the increased stagnation of the rates of corrosion progression.
An inhibitor may also be known as a rust inhibitor or a corrosion inhibitor.
Corrosionpedia explains Inhibitor
Corrosion inhibitors are chemical substances that are negatively enacting catalysts. They can be classified as antioxidants, inducers or enzymes. Inhibitors increase the activation energy required for a corrosion reaction to take place, thereby making it more difficult for the required energy levels to be attained naturally, and encouraging corrosion cessation.
