A non-conformal phosphor coating causes thickness of phosphor coating layer variation and inadequate color uniformity.
The spin coating causes film shrinkage due to compression and fast evaporation of water from the thin films.
More importantly, the POB/CuAl composite coating causes minimum damage to its frictional counterpart, which is significant for its application as a lead-free bearing surface.
Temperature variance becomes much larger for aluminum coating than silver because absorption α of aluminum is larger than silver, indicating that aluminum coating causes larger deformation of CCM surface than silver coating.
The coating causes the electrochemical standard rate constant of the redox system to be reduced by one to two orders of magnitude.
This distance can actually be significantly larger than the actual droplet size, because the requirement for spotting onto the same position repeatedly to achieve sufficient matrix coating causes significant loss of resolution due to small positioning inaccuracies.
