| Popis: | Squeeze casting process of Zamac 5 for obtain faucets enables higher productivity associated with better dimensional characteristics. In this process, the die cooling system can influence the solidification of the alloy and its properties. This study evaluates the influence of die temperature on solidification under pressure from Zamac 5. Pieces were removed from the die at several temperatures. Samples were evaluated by neutral salt spray corrosion, optical microscopy and microhardness. The results show that the corrosion is related to the porosity defects, which was most intense in part regions which solidified lastly. These regions also showed different results of microhardness. However, the behavior of the samples was similar in the range of die temperatures studied. |
