Stripping off coating from carbide surface

Sir,
iI working for PVD coating pvt.company.
we have almost all type of coating strippers which helps in striffing coating for HSS and other steel surfaces,
but we are facing problem in stripping from CARBIDE SURFACE.
we cannot use our regular stripping solution with carbide as a base material.
Do you have any solution which and what stripper can be use so as to avoid etching of base carbide surface?

You could try blasting with glass beads or aluminum oxide. Very hard and thin coatings such as PVD TiN or TiAlN come off due to their brittleness.
