| Abstract: | Investigation was made on the material and its process for extrusion casting piston, wear resistance, Al-Fe metals composite and cooling oil groove forming. The piston with cooling oil groove by Al alloy extrusion casting was tested successfully for single bore for 410 hours according to the requirements of 1000～1200 horse power disels. The life of the wear resistance can be increased by 5 to 10 times. |
