Corrosion Rate
Corrosion rate indicates how fast a material corrodes. It is measured as thickness loss per time or mass loss per area and time. Environmental factors such as temperature, flow, and media influence this rate.
Physicochemical Mechanism of Action
Corrosion rate describes the speed at which a material is destroyed under the influence of corrosive agents (such as air or water). This process is mostly chemical and leads to material thickness loss or a change in surface mass.
Metallurgical Relevance & Welding Risks
High corrosion rates can lead to rapid material wear, cracking, and distortion. This can significantly shorten the service life of components and machine parts and create safety hazards. In welding, it is particularly important to interrupt or slow down the corrosion process to protect the material from further destruction.
Workshop Practice & Action Guidelines
To control and reduce corrosion rate, take the following measures:
• Use corrosion-resistant materials or protective coatings.
• Keep the material dry and protect it from chemical attack.
• Regularly inspect the surface for signs of corrosion and perform necessary cleaning.
• Use corrosion-resistant weld joints and materials.
