Abstract
The present study focuses on fabrication of Fe-Cr-Ti alloy HVOF coating with varying Cr and Ti content and investing the impact of Cr and Ti content on mechanical and corrosion properties. Mechanical performance metrics, including adhesion pull-off strength, and corrosion characteristics, were compared. 10 weight percent of chromium was found to enhance the hardness, adhesion pull off strength, and fracture toughness by 22 %, 23 %, and 17 %, respectively. On the other hand, the addition of 10 weight % titanium increased the hardness, adhesion pull off strength and fracture toughness by 59%, 7% and 50% respectively. Considering all the performance factor for the alloying element content up to 10 weight %, it is concluded that titanium appears to be more important than chromium in terms of mechanical properties and Cr appears to be more important in term of corrosion
