Corrosion resistance

Various aspects related to the corrosion resistance of Inconel 625 are studied. These include its oxidation resistance, crevice corrosion, pitting corrosion, and stress corrosion cracking. Compared to Inconel 600, the corrosion resistance of Inconel 625 is higher. It can be used in marine and aerospace industries.

In order to improve the corrosion resistance of Inconel 625 coating, high speed laser cladding technique was used. This technique significantly improves the corrosion resistance. The process was optimized to achieve maximum corrosion resistance. The coatings were processed at ultra-low dilution rate. The dilution ratio was 12%. The coatings had a thickness of 534.4 mm.

The cladding was tested in de-aerated 3.5 wt% NaCl solution. The corrosion performance of the wire laser clad Inconel 625 coating was compared to the wrought Inconel 625 alloy. The results showed that the wire laser clad Inconel-625 coatings had higher corrosion resistance than the wrought Inconel-625 alloy. It is possible that the cladding process may have altered the chemical composition. The clad layer may be formed with a hexagonal close-packed structure. The resulting surface finish is also good.

Microstructure of the clad beads was investigated by optical and scanning electron microscopy. These results showed that the clad beads had crack-free microstructure. It was also observed that the clad beads had a flat top surface. The top surface of the clad beads had a corrosion product thickness of 0.1 mm. The corrosion product may be due to the formation of a dense silicon oxide protective film. The results were verified by chemical analysis.

The cladding process was optimised to achieve maximum corrosion resistance. The dilution ratio of Fe was determined to be 12%. The corrosion performance of the wire laser nitinol Inconel-625 coating was lower at 12% dilution.
