0.0001"/ pass in itself is not a bad thing, for this type of coating I would recommend keeping deposit per pass below 0.0005" anyway.
At 1mm/s traverse and 100g/min feed rate on 10" diameter your deposit efficiency sounds painfully low. I would expect 10X + that. I can not see your cooling set-up, spray angle effecting it this much.
I would conduct a deposit efficiency test and first establish whether you are getting reasonable efficiency in more ideal conditions.
Quote:I had obtained few advises which I am going to try:
1) reduce spray angle
2) Increase transverse speed to 2mm/s or 3mm/s
3) extend spray beyond coating area
Generally good advice
"2) Increase transverse speed to 2mm/s or 3mm/s" well really the traverse speed should be set so that the coating layers just overlap without "barber pole spirals". Set part rotation and traverse speed so that on each rotation the gun moves relative to part a bit less than the spray footprint width. Set the speeds so that you achieve around 0.0002"/per pass if possible, if not go as low as possible. Doing this will go some way to help you control temperature.
