Abstract

The offshore industry faces challenges with corrosion resistance in hydraulic cylinders used in marine environments Thermal spray coating appears to be a promising technique for replacing electroplated coating in many applications but the performance of thermal spray coatings in highly corrosive environments must be improved In the present work a new sealing method for HVOF WCCoCr coatings for their application on hydraulic cylinders for marine environments has been tested The method consists of applying solgel solution that can penetrate fill and thus seal the pores and cracks in the coating The sealed coatings have been tested with and without posttreatment and compared with assprayed coatings Opencircuit potential OCP and tribocorrosion tests in 34 NaCl were performed to evaluate the performance of the sealing method Both tests showed that the sealed coatings had the best performance
