Electropolishing – the best way to prevent rust | Limat | 06.04.09


The following is a common problem is almost every industry: surfaces and tools are crafted out of stainless steel, in hope to prevent  rapid corrosion and rust accumulation, and while certain alloyed are, supposedly, rust-resistant, such surfaces still have to undergo polishing in order to survive in harsh conditions, which often include exposure to chemicals and moisture.

The passivation process is meant to improve metals' resistance to corrosion, and this is also one of the things  electropolishing does. The latter has been proven to be 30 times more effective than any other method of passivation; and two main factors have made electropolishing the benchmark method of the industry: its ability to create even surfaces and its ability to enhance the surfaces' resistance to bacterial accrual.

Metal surfaces tend to be “germ friendly,” and the danger of bacterial accumulation increases when metals are exposed to chemicals and humidity, which are rust conducive. Electrochemical polishing tackles this problem better than any other passivation method: electropolishing strips the surface of any residues an asymmetries and significantly reduces the number of surface points  exposed to chemical and moisture build-up. As the process runs across the surface in a uniform manner, any hidden or problematic parts of the surface emerge as durable as part which were easily polished – hence electropolishing's immense advantage over other methods.   

Limat, like other international electropolishing companies, can attest to the growing list of parameters which set electrochemical polishing apart from other mechanical and superficial metal polishing methods. Experience has proven that electropolishing is the most effective method of preventing rust and corrosion.
