Example Embodiment
[0035] Example 1: Such as figure 1 As shown, a method for preparing a diffusion couple of a tool and a workpiece based on laser cladding bonding includes the following steps:
[0036] A. Choose the cemented carbide tool YG6 from Zhuzhou Cemented Carbide Factory as the tool sample 1, and the gray cast iron HT250 for the cylinder block of Weichai Power Engine as the workpiece sample 2.
[0037] B. Cut the tool sample 1 into a trapezoid structure of 16mm×8mm×6mm by wire cutting, and cut the workpiece sample 2 into a trapezoid structure of 16mm×8mm×4mm by wire cutting;
[0038] C. Cut the sample obtained in step A and step B twice, so that the two samples after cutting can form at least one groove or cavity after being bonded, which is used to place the cladding powder and facilitate the metallurgical state of the two samples Firmly combined
[0039] D. The surface to be bonded and the surface to be cladding of the tool sample 1 and the workpiece sample 2 obtained in step C are sequentia...
