Description

technical field

[0001] The technology relates to the fields of additive manufacturing and current-assisted processing, especially a current-assisted friction additive manufacturing device and method. Background technique

[0002] With the continuous enhancement of people's awareness of environmental protection, reducing resource consumption and environmental pollution has received great attention. As an advanced additive manufacturing technology, friction additive manufacturing is based on the principle of gradually accumulating metal materials to manufacture solid parts. It has the characteristics of high efficiency, high quality, low energy consumption and low pollution. This technology uses friction coating technology to prepare and accumulate solid parts layer by layer. Friction coating technology is widely used in aerospace material connection, petrochemical and additive manufacturing because it can obtain a welding layer with good bonding integrity on the surface of th...

Examples

Embodiment 1

[0037] Such as figure 1 As shown, the aluminum alloy consumable rod 2 is fixed on the friction coating equipment 1 , the positive electrode of the current generating device is connected to the aluminum alloy consumable rod, and the negative electrode of the current device is connected to the substrate material which is a steel plate 3 .

[0038] When preparing a single layer, start the friction coating device first, and then start the current generating device 4 (power supply) to generate current. specific reference figure 1 , first install the aluminum consumable rod used for friction coating on the friction coating device, then fix the steel plate as the substrate material, then the coating material touches the surface of the steel plate while rotating continuously, and at the same time turn on the power of the current generating device, and apply the current synchronously field. Among them, the angle between the aluminum consumable rod and the vertical line on the surface...
