Effect of Water-Based Emulsions on Corrosion in Bearing Ring Manufacturing

This study evaluates the performance of a semi-synthetic emulsifiable fluid with anticorrosive properties, tested as a potential substitute for temporary corrosion protection during the production of thrust bearings. Samples were exposed to 48 h in a condensation chamber in accordance with ČSN 03 8131. The fluid provided partial protection; however, initial signs of pitting corrosion were observed. Although the emulsion reduced the extent of corrosion, it was not fully effective under the tested conditions, indicating the need for further formulation improvements or alternative protective measures.
