Notes:
The W coatings were prepared by applying the vacuum plasma spraying process (VPS). The phasecomposition, microstructure and laser irradiation property were characterized by XRD, SEM and laser.Results showed that no tungsten oxide appears in the coatings whose phase composition is similar to theoriginal powder. A better melting state of the coating can be obtained by using the finer powder. Thedeposition efficiency of the coating is higher in the cases of a higher H2 flow. There is a pitch whose size isabout 100μm when the substrate was irradiated by laser. However, there is clearly no change for the Wcoating surface which was also irradiated under the same condition. It indicates that the laser irradiationresistance is improved significantly for stainless steel after being deposited with W coating
