<p><P>PROBLEM TO BE SOLVED: To provide a method for working the inner surface of a cylinder where, when finish machining such as honing is performed after the formation of a thermal spray coating, the peeling of the thermal spray coating in the edge part in the axial direction of the inner surface of a cylindrical part is prevented. <P>SOLUTION: A rough surface 17 is formed on the inner surface 5 of a cylinder bore, thereafter, a thermal spray coating 7 is formed thereon, and subsequently, a tapered face 101 is worked to the edge part on the side of a crank case 9 in such a manner that the inside diameter of the edge part on the side of a crank case 9 at the inner surface 5 of the cylinder bore is made large compared with the inside diameter of the other part. After the working of the tapered face 101, honing is performed to the sprayed coating 7. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
