Abstract
The invention relates to a making method of a firearm silencer. The method comprises the steps that S1, a multi-layer-mesh porous material is sintered to be made into a multi-layer porous substrate mesh; S2, a porous ceramic material is added to the surface of the multi-layer porous substrate mesh, and a multi-layer porous silencing mesh is formed; and S3, the multi-layer porous silencing mesh is wound and welded, and a round-tube-shaped product is formed, wherein the inner layer of the product is made of the multi-layer-mesh porous material, and the outer layer of the product is made of the porous ceramic material. According to the porous silencer made of the multi-layer-mesh porous material and the porous ceramic material, a larger number of small holes which make the interior and the exterior communicated are formed in the porous silencer, when sound waves are emitted into the porous silencer, vibration of air in the holes can be caused, sound energy can be converted into thermal energy to be consumed due to viscous resistance of the air and friction and thermal conduction action between the air and hole walls, and therefore the sound waves are rapidly damped in the porous silencer, and a good silencing effect is achieved. In addition, the making technology is simple, and the making cost is greatly reduced. The invention further provides the firearm silencer.
