Cold Sprayed Ti-Based Protective Coatings on Carbon Steel for Plate Heat Exchangers

摘要

Titanium (Ti) based coatings on carbon steel plates are being investigated in the study in terms of heat transfer performance. The coatings were fabricated from powders using a cold gas dynamic spray system (CGDS). Heat transfer experiments were performed on a simple single plate heat exchanger set-up. Test results showed that the use of Ti-based coatings on carbon steel plates instead of using pure Ti plates for heat exchangers in seawater applications is quite promising. Not only that the Ti-based coatings have potential in terms of corrosion protection, they also have the potential of having better heat transfer performance than plain Ti or stainless steel plates.
