Low wear guide rod for pneumatic actuator and its surface technology
The invention discloses a low wear guide rod applied to a pneumatic actuator and its surface process, which comprises the following steps: (1) providing a carbon steel base material for the guide rod, placing the polished surface in an acid solution, cleaning and drying; In step (2), use the Hall gas ion source to bombard the pretreated substrate with gas, and in step (3), use the Nd: YAG pulse laser drilling machine to punch round holes on the substrate surface; Step (4) ZrB2 target and MoS2 target form a solid coating on the surface of the substrate, and then obtain the guide rod after surface processing. The guide rod for pneumatic actuator has excellent wear resistance, corrosion resistance, self lubrication and hardness.
Sovereign projects: 1. The pneumatic actuator adopts the low wear guide rod preparation process, including the following steps: step (1), provide the guide rod carbon steel substrate, polish its surface, place the polished carbon steel substrate in acid solution, fully clean and dry, and obtain the pretreated substrate. Step (2) Use the Hall gas ion source to bombard the substrate and strengthen the pretreatment of the substrate surface. The working voltage of the Hall source is 500~1800V, 600~8000~℃, and the bombardment time is 2~3h. Step (3) Nd: YAG pulse laser puncher is used to punch holes (2) on the surface of the substrate. The hole diameter is 0.06-0.1mm, and the area ratio of the surface textured substrate is 10%~25%. Step (4) The ZrB2 target and MoS2 target are deposited on the surface of the substrate by using the magnetic filtration deposition technology, and a solid coating is formed on the surface of the substrate, and then the guide rod after surface processing is obtained.
