Friction damage is very easy to occur when the interference fit is disassembled.It is found that adding laser pitting texture on the interference fit interface can significantly reduce the disassem-bly damage.However,due to the fact that the interference fit interface with texture is still in dry fric-tion disassembly state,when the interference amount is too large,the texture interface will still form serious disassembly damage.Therefore,based on the principle of rock seepage,this paper adopts seepage test to introduce lubricant into the fit surface to achieve the lubrication disassembly of inter-ference fit surface,and analyzes the damage of the fit surface during the disassembly with large inter-ference.The results show that the pitting texture can be processed on the interference fit interface to retain the melt layer,and the lubricating oil can be introduced into the fit surface under certain seep-age conditions to form boundary lubrication or mixed lubrication,and the honeycomb texture has a more prominent seepage effect.In the state of large interference,when the contact pressure is 200 MPa,the dry friction disassembly with honeycomb texture containing melt layer can reduce the disassembly damage compared with that without texture,but the maximum damage depth is still 76.7 μm.The damage of seepage lubrication disassembly with honeycomb texture containing melt layer is significantly lower than that of dry friction disassembly with honeycomb texture containing melt layer,which can achieve non-destructive disassembly.
