Evaluation with Surface Analysis Equipment, of Casting Defects in Cast Iron Articles (review)
Authors have reported theses concerning the cast defect for publication in journal of Japanese Foundry Engineering Society and AFS Transactions. This is a review of these reports. There are various factors in the casting defect that occurs in the article of casting metal, and specific of the generation factor is difficult. Moreover, it is necessary to decrease the casting defect to reduce the cost of goods manufactured and energy of production. It is effective to the evaluation and the classification method of the casting defect to employ Scanning Electron Microscopy with Energy Dispersion Spectrometer (SEM-EDS) and Electron Probe Micro-Analysis (EPMA). Casting defects chose the one that the incidence was high and specific of the generation factor is difficult, and the pinhole defect and inclusion defects were classified according to the generation factor, and penetration defect showed the relation of physical factor, chemical factor, and those interactions, and examined whether specific of the factor was possible by the surface analysis equipment about other defects (Blow hole, Shrinkage, Orange peel, Cold shut, Cracks and Veining).
