This study analyzes the effects of laser remelting on the morphological structure and adherence of flame-sprayed PEEK coatings on stainless steel. Different types of lasers were used with wavelengths of 1.064 mm (Nd:YAG), 10.6 mm (CO2), and 0.88 mm (diode). It was found that the longer the wavelength, the more compact the coating, but the less well-adhered. By making adjustments to compensate for the wavelength-dependent absorption coefficient of PEEK, both coating properties were improved.
