摘要： PROBLEM TO BE SOLVED: To provide a cylinder block contributing to improving fuel economy and durability by being equipped with a sliding surface fully satisfying in scuffing resistance and coefficient of friction.
SOLUTION: After forming a thermal-sprayed layer 3 by thermal spraying a metallic material on the inside face 2 of a bore of a block base body 1 of a cylinder block made of light alloy, a sliding face 4 is made by honing the surface of the thermal-sprayed layer 3. By adjusting the honing condition and the thermal spraying condition, a pit area rate Sp of the sliding face 4 is kept within the range of 5-14%, and surface roughness [Rk+Rpk] expressed by the sum of effective load roughness Rk and an initial wear height Rpk is made 0.9μm or lower. By keeping the pit area rate Sp within the range of 5-14%, oil maintaining capacity becomes sufficient and scuffing resistance is improved. By making the surface roughness [Rk+Rpk] 0.9μm or lower, the value of the coefficient of friction is sufficiently low, and fuel economy is improved.
