Preparation method of marine gradient copper alloy heat exchange tube

The invention discloses a preparation method of a gradient copper alloy heat exchange tube for ocean. The preparation method comprises the following steps: preparing a material 1; preparing a material 2; carrying out solid modeling on the marine gradient copper alloy heat exchange tube, and carrying out characteristic layering treatment on the model; preparing the inner pipe and the outer pipe by utilizing an additive manufacturing system, and finally, machining the marine gradient copper alloy heat exchange pipe by adopting linear cutting equipment and a numerical control milling machine. According to the gradient copper alloy pipe with the strong outside and the tough inside, the abrasion resistance of the gradient copper alloy pipe is improved on the premise that it is guaranteed that the antibacterial property of the gradient copper alloy pipe is not greatly reduced. 本发明公开了一种海洋用梯度铜合金热交换管的制备方法，包括：材料1的制备；材料2的制备；对海洋用梯度铜合金热交换管进行实体建模，将模型特征性分层处理；再利用增材制造系统对内管、外管的制备，最后，采用线切割设备及数控铣床对海洋用梯度铜合金热交换管进行加工。本发明提供了一种外强内韧的梯
