Hi Laurent
Quote:Could you please confirm whether 45VFNS (which is also used as a bond) could be applied with no primary 450NS bond coating?
45VFNS can be used without a bond coat. It is designed for very thin coatings (max 0.4mm). Metco 45C-NS can be used as a base coat to extend coating thickness limitation.
Quote:It appears that our powder regulator went down and both powder selection went wrong, therefore 45VFNS only has been applied.
Final thickness of 45VFNS is of 0.30mm.
Considering the part I would expect the coating to be covered by aerospace specifications/procedures and traceability. I would highly doubt this deviation would be allowed even if technically thought to be OK.
