Failure Analysis of 286L -Type Marine Diesel Engine Piston
Abstract：The physical and chemical test was used to study the internal quality of the 286Ltype marine diesel engine piston. This paper described mierostructure characteristics and internal defect grades of the failure piston of the marine diesel engine. Based on the fracture surface morphology and the heat treatment process of the failure piston, it was found that the structure defects and the internal stress in the piston were the main reason causing the piston failure. And some suggestions were given to prevent against similar failures.
