TSA coating applied to 316L pipe

[MIKEOKEEFE63]

Searching for a DFT gauge capable of reading Thermal Sprayed Aluminum Coating thickness on 316L Pipe. The Fischer Phascope PMP10 w/ESD20Zn probe apparently is capable however I cannot find any back-up to support this.
Looking for any information/confirmation/experience regarding this particular unit for Thermal Sprayed Aluminum Coating thickness on 316L Pipe....any alternative equipment referrals would also be appreciated.

Thanks,

Hi Mike
I settled an TSA coating on 316, and it was possible to measure the coating, with an NDT ultrasonic gauge, the problem was the thickness differences in the base metal, but we measured first base metal thickness and after TSA coating, I measured the total thickness (base material plus Al coating), in the same place, and you can obtain TSA thickness for difference.

i have applied 86WC10Co4CR hvof coating on SS 316 ,how can i measure coating thickness ????whch kind of DFT meter will be helpful ??/ i have tried with eddy current based and electromagnetic based DFT meter but none of them give me perfect result..

thanks in advance
