Your steel experts
At RUBIG, we are the experts in steel and have been working with it as a material for more than 70 years. We use our wealth of experience and comprehensive expertise for the benefit of our customers. In cases of damage, our experts are also tasked with carrying out material investigations.
We support and guide you: process development, using corrosion as an example
One problem faced by many of our customers is corrosion. The effects of corrosion can cost around 3-4% of the GDP in industrialised nations. Whether steel corrodes depends on various factors, such as the interaction between the material’s composition, the heat treatment condition, the coatings used and the environmental conditions.
From a defective component to one ready for mass production
In the first stage, RUBIG experts assess the initial condition leading to the corrosion damage. Various tests are then carried out to determine the cause of the corrosion. The tests employed include the neutral salt spray test, current density/potential measurement and impedance spectroscopy. In addition, by measuring frictional corrosion, the combination of corrosion and wear can be checked. From the test results, our experts are able to determine suitable and practicable preventive measures. That might be a special hardening process, for example, or a specific coating. In the next stage of the process, the modified component undergoes corrosion tests once again, and its corrosion resistance is determined. Finally, the customer receives a corrosion-resistant component, ready for mass production.
Important facts to bear in mind: Unalloyed or low-alloy steel corrodes after just one to two hours in a neutral salt spray test. However, in the same spray test, steel treated by RUBIG, with a Duplex DLC Xtended® coating for example, withstands corrosion for up to 1,000 hours or more.
