Silver plating surface stains can compromise the appearance of finished components even when the underlying material is defect-free. This case study explains how contamination, insufficient cleaning and plating bath conditions can lead to staining and incomplete silver coverage. Read the full analysis to learn how to prevent these issues.
Intergranular casting cracks can occur during cooling when shrinkage stresses exceed the mechanical strength of the alloy. This case study explains how grain boundary phases and thermal contraction differences can lead to sudden fractures after casting. Read the full analysis to discover how to prevent these failures.
Investment casting plaster inclusions can significantly reduce surface quality and lead to defects that are difficult to remove during finishing. This case study explains how incorrect investment preparation and insufficient stabilization time can weaken the mold and promote inclusions during casting.
