Systematical investigation on the microstructures and tribological properties of Fe-Al laser cladding coatings

Increasing the tribological properties of the 1045 steel is significant to expand its application. Herein, we developed a high energy ball-milling process to prepare Fe-Al alloyed powders, followed by a laser cladding process to deposit a Fe-Al coating on the surface of 1045 steel substrates, which can dramatically increase its tribological properties. The effect of the ball-milling time on the microstructures and compositions of the Fe-Al...
