Hello,
Background:
High pressure die casted (material AlSi8Cu3(Fe)) parts are in contact with
steam (water, nothing else). These parts are turning grey/dark grey in 15
minutes. Before they are in contact with steam they are campletely clean
and shiny.
Questions:
What is hapenning at surfaces of these parts?
What is this grey material/phase?
Is it possible this grey material not to appear at the surface of these
high pressure die casting parts.
I really appreciate if someone have got some answers to my questions.
Thank You.
