The Effect of Scanning Velocity on AISI 304 Stainless Steel Laser Cladding Coatings

摘要：

　　Single and multi pass AISI 304 stainless layers tightly combined with substrate was obtained by laser cladding on the surface of 45 steel using the way of presetting powder.Effect of different scanning velocities on cladding layers was analyzed and interpreted in this paper; influence of scanning velocities on dilution rate was also acquired,the dilution rate come up to a maximum value which is 11.1% when the scanning velocity reached 800 mm/min,what is more,immersion test shows that scanning velocity has little effect on the weightlessness rate.Besides,XRD patterns shows that the cladding layers composed of ferrite and austenite phases.
