Paper Title:
Study on Behavior of Ni-Based and Fe-Based Hardfacing Alloys in Plant Valves with Laser Cladding
  Abstract

Two new kinds of Ni-based and Fe-based alloy power have been developed. Both kinds of power have been successfully coated by laser cladding on the surface of stainless steel as strengthening layers. The morphology and microstructure of these coatings have been analyzed by SEM and XRD, the mircohardness, wear and corrosion resistance of Ni-based and Fe-based laser cladding coatings have been measured respectively. The analysis reveals that both coatings with smooth and successive surfaces and homogeneous morphology have been obtained under the proper laser processing parameters; besides, Ni-based and Fe-based coatings have fine, well-proportioned and dense microstructure, and better joints with the substrates, respectively. So the results indicate that Ni-based and Fe-based alloys can supersede the cobalt-based alloys in the certain conditions.
