tried blasting only to found out deflection

Hello everyone
how to removal 45VFNS coating after spraying, because some parts didn't fulfill the requirement of customer and should be re-coated again. We've tried blasting only to found out deflection of parts. The part substrate is Ni-based alloy with thickness of 0.5-0.8 mm and coating area is less than 9X15 mm. Is there any chemical method to removal this coating?

Hi Jadefowler
45VF is a Co25Cr10Ni8W powder, so is very difficult to chemical remove it, so you must remove it mechanically, is recommended not to use of chemicals, is very important for the environment cure
