文摘
- •
Microstructures changed from hypoeutectic to hypereutectic with scanning speed.
- •
Volume fraction of martensite increased with scanning speed.
- •
Wear resistance of the optimized layer was increased by 29.76 times.
- •
Oxide films formed on the alloyed surface of the layers substantially enhanced the wear resistance.
- •
Microstructure affected the crack or fracture behavior of the matrix on loading.
