Porosity - Casting defects in the block window II - Casting defects


Figure 1: Porosity-type casting defects in the block window and on the exterior surface.

Defect name: Porosity
Record No.: 1982
Type of defect (Internal/Surface): Internal, surface
Defect classification: Casting defects
Steel name: Steel
Steel composition in weight %: No data.
Note:  In Figure 1, porosity-type casting defects occur again in the zone of the rotor block window. The rotor block window open porosities do not occur in all windows. On the exterior surface of the part porosities are visible. The porosities on the exterior surface are due to the mould and paint insufficiently dried before casting. In Figure 31 we can also remark that the superior side of the block after mechanical processing is irregular due to the presence of macrocavities casting defects.
