PURPOSE:To obtain a connecting rod which is light and excellent in bearing performance by forming flame spraying layers of Al-Sn base, Al-Pb base, or Al-Sn-Pb base alloys more than 20mum thick on bearing surfaces of a large end surface and a small end surface. CONSTITUTION:Al-5 percent Pb or Al-10 percent Sn alloy powder is flame sprayed to a connecting rod main body portion 1 of a connecting rod manufactured by using S55, a bearing surface 8 of a cap 4 and the surface of a cylindrical portion of a small end portion 3 by Meteco Corp.'s plasma flame spraying device to form flame spraying layers (9), (10) 200mum thick, which is machined to be 150mum thick. |
