Document Type and Number:
Japanese Patent JP2007277607
Kind Code:
A
Abstract:
To suppress the stress caused when a molten material deposited on an end in the axial direction of an inner surface of a cylinder after the thermal spraying is solidified and condensed.
A roughened surface 9 consisting of screw-shaped uneven parts is formed as the pretreatment before depositing a spray deposit film 30 on an inner surface 5 of a cylinder bore. The roughened surface 9 roughens the surface roughness of a crank case side end 13 and a cylinder head side end 15 which are ends in the axial direction of the cylinder bore 3 more than the surface roughness of a center portion 17 in the axial direction.
