Does PVD conceal defects in the stainless steel?

No, therefore, it is essential that the stainless steel substrate undergoes rigorous quality inspection to ensure it is entirely free of defects and meticulously cleaned prior to PVD colouring.

The PVD coating, which ranges from 0.35 to 5 microns in thickness, forms a robust molecular bond with the stainless steel, enhancing its surface hardness. Due to its exceptionally fine nature, the coating does not conceal imperfections but instead accentuates the underlying finish, allowing it to be clearly visible.
