WC-CO-CR hvof coating thickness measurement on Base SS 316L

Dear HVOF coating expert,researcher

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..
all DFT meter shows false reading ??is there any DFT meter available in the world

which can measure coating thickness of conductive material wc-co-cr on base substrate non ferrous & conductive SS 316 material ??/



thanks in advance

Hi Virani
Time ago I measured TSA thickness on AISI 316 with NDT ultrasonic thickness gauge, in order to know all particular thickness and to know coating thickness by difference between before coating and after coating reading, important to sign the exact position where you take the measure before and after coating, I think that could work with Wc10Co4Cr with an adeguate point calibration for the coating and base materials
Best regards

Hi loriolo,
Thanks for sharing valuable information
as per my knowledge ,after coating all marks will be disapear ,is there any tricks which can work to check coating thickness ???/

Hi virani
only meccanical measured points or doing a metal sheet mask with positions
Best regards
