FIELD: process engineering.
SUBSTANCE: invention relates to machine building, particularly to finishing of ICE liners. Liner inner surface is subjected to rough and semifinish honing to surface roughness Ra=1.15…2.35 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: longer life.
