摘要： Crankshaft bearing cap 1 presenting on one of its faces a semi-cylindrical notch (2), formed by powder metallurgy with an iron powder blend molded by compaction and sintering, and partially infiltrated with Cu, being the area (A) adjacent to the area A around the notch 2, the one with highest Cu content. A method for manufacturing main bearing caps by infiltration of Cu comprising the steps of placing the molded cap so that the axis of the semi-cylindrical notch extends in a horizontal direction and the notch cavity is in the upwards position. Placing high Cu content tablets on the upper face of the cap and on the cylindrical arch and sintering of the cap and Cu tablets system.
