Evaluation Method of Cavities Defects for Metal Die Casting
摘要
Abstract
Cavities are common defects in the production of die casting. The porosity of metal die casting measured by using quantitative metallographic method was discussed in this paper. The quality of castings was evaluated according to the measured results of porosity. The accurate porosity results based on preparing good sample, and the effects of the coatings and the flow of molten metal on the gas porosity were researched.关键词
