A restore method for wearing diesel cylinder jackets is composed of heat process, internal surface activation and electro-plate orderly in which the internal stress not good for using it eliminated by heat process, the distored metal lattice of the jacket resulted from long time mechanical friction is recovered, finally, luboil penetrated into the jacket is eliminated. The surface activation process in the jacket is to grid its surface to smooth, then to eliminate the oxide layer on it by physical or chemical methods (current or acid cleaning), electroplating is under gone with bivalent Fe ions solution, with the advantage of restoring wering cylinder jackets to original size to prolongs its service time. |
