Embodiment Construction
[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] The forging die that needs to be prepared in this specific embodiment is the lower die of a common forging die, and the cross-sectional structure to be welded is as follows: figure 1 As shown, its preparation method comprises the following steps carried out in sequence:
[0033] a. Use the newly made 5CrNiMo mold as the matrix, and reserve a margin on the surface of the matrix cavity and form a wave shape. Such as figure 1 shown.
[0034] b. Using the automatic gas shielded surfacing welding process, the transition layer is surfacing on the surface of the mold base cavity, and the transition layer is evenly distributed.
[0035] c. Use one-step spray welding to spray and weld self-fluxing alloy powder on the surfacing transition layer to form a surface strengthening layer. The hardness and toughness of this layer are higher...
