Electro-Galvanizing from a Purified Ammonium Sulphate Leach of Anaconda Zinc Calcine

Ever since the introduction of metal products into our civilization, especially those of iron and steel, man has been confronted with the problems of corrosion prevention. As the agents which are conducive to cor­rosion cannot be completely eliminated, it has been necessary for man to develop processes and materials that will retard the degeneration of the metals that are so important to our industrialized world

Design of Test Parts to Characterize Micro Additive Manufacturing Processes

AbstractThe minimum feature size and obtainable tolerances of additive manufacturing processes are linked to the smallest volumetric elements (voxels) that can be created. This work presents the iterative design of a test part to investigate the resolution of AM processes with voxel sizes at the micro scale. Each design iteration reduces the test part size, increases the number of test features, improves functionality, and decreases coupling in the part. The final design is a set of three test parts that are easy to orient and measure, and that provide useful information about micro additive manufacturing processes
