FIELD: process engineering.
SUBSTANCE: invention relates to reconditioning of diesel cylinder liner inner surfaces. Cylinder liner inner surfaces is honed one time and subjected to air vibrodynamic processing. Honing is made to roughness Ra≤2.5 mcm. Then, said surfaces is blasted by steel balls to roughness Ra≤0.5 mcm, mean depth of recess Rvk≤1 mcm and relative reference length of profile tP50=85%.
EFFECT: higher wear resistance.
