摘要（英）：

The invention discloses iron-based alloy powder for a high strength and toughness laser deposited coating in the technical field of alloy materials. The iron-based alloy powder comprises the following components: 0.60 to 1.00 percent of C, 0.35 to 0.70 percent of Si, 0.30 to 0.60 percent of Mn, 5.00 to 7.00 percent of Cr, 2.50 to 4.00 percent of Ni, 1.50 to 2.50 percent of Mo, 1.00 to 1.50 percent of W, 0.70 to 1.00 percent of V, 0.20 to 0.40 percent of Ti, 0.50 to 0.70 percent of B, 0.20 to 0.40 percent of Nb, 0.10 to 0.30 percent of Ce and the balance of Fe. The iron-based laser deposited alloy coating without cracks in large area can be obtained without pre-heating and post thermal treatment, the deposited alloy coating has high hardness which reaches 62 to 67HRC, and the yield strength reaches 1,700 to 2,000MPa.
