AbstractPhase structure of sputtered Ta coating in the negative glow space and LPH effect were explored. The whole coating/substrate system is substrate -> physically gas-absorbed Fe surface -> oxygen-enriched TaOx layer -> amorphous Ta -> alpha and beta dual phase -> single alpha phase. After LPH course, microstructure of Ta coating shows intact, only a few cracks emerge after 100 laser pulses, exhibiting thin HAZ but thick Fe/Ta ICZ, without martensitic transformation. For the electrodeposited Cr coating, continuous thermal stresses produce many extra micro-crack, substrate oxidation and martensitic transformation, leading to crack propagations and final bulk delamination, without any ICZ.
