The comparative example is different from the example 2 in that the comparative example does not carry out the step (2), the heat treatment is directly carried out after the aluminum tin 20 copper surface deoxidation pretreatment of the complete step (1), the aluminum tin 20 copper composite roll and the titanium coiled tape are compounded, the aluminum-titanium diffusion annealing is carried out, the annealing temperature in the aluminum-titanium diffusion annealing is 320 ℃, and the tin precipitation on the aluminum tin 20 copper surface is shown in figure 4. As can be seen from fig. 3-4, the tin deposition on the surface of the aluminum-tin 20 copper of the non-wrapped composite aluminum layer is more serious than that of the aluminum-tin 20 copper of the wrapped composite aluminum layer, i.e., the tin leakage of the aluminum-tin 20 copper is effectively blocked by the wrapped composite aluminum alloy at an increased heat treatment temperature.
The wear resistance and interfacial composite strength of the products of example 2 and comparative example 2 were tested and the results are shown in table 1:
TABLE 1
Figure BDA0003655081630000071
From the above, after the aluminum-tin 20 copper surface layer is wrapped by the composite alloy aluminum layer, the tin element precipitation phenomenon is inhibited, the tin leakage problem is solved, and the wear-resisting level, the composite interface strength, the elongation and the like are obviously improved.
The parts or structures of the invention which are not described in detail can be the same as those in the prior art or the existing products, and are not described in detail herein.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
