mm。
Another object of the present invention is to provide a kind of metal foam sheets for producing easy lifting metal foam radiating effect
Roughening process, to overcome the deficiencies in the prior art.
It is another object of the present invention to what is be achieved in that：
A kind of metal foam sheets roughening process, it is characterised in that：First it is that metal foam sheets substrate surface treatment is clean, uses
Metal wire rod is sprayed on metal foam surface by machine.Wherein, spraying metal materials machine requirement be treatment effeciency it is high, to foam
Metal piercing power is strong.
Another object of the present invention can also be solved using following technical measures：
Used as more specifically scheme, metal wire rod is aluminium wire, stainless steel wire or copper wire（But do not limit to above different materials）.
The a diameter of 1.5mm to 2.0mm of metal wire rod.
Beneficial effects of the present invention are as follows：
（1）The opening of cylinder metal foam of the invention is welded and fixed in the way of 3D printing metal powder, and metal powder will not be blocked
The loose structure of metal foaming material, makes it keep original porous heat sinking function, the cylinder metal foam phase with prior art
Than its better heat-radiation effect；
（2）Metal foam sheets of the invention increase metal foam structures surface area by roughening treatment, greatly promote its radiating effect
Really；Its rough surface is additionally, since, and adhesive force is strong, is easy to it be welded by 3D printing metal powder.
