Improving corrosion resistance low carbon steel with super duplex stainless
Researchers from Oregon State University, USA, have studied improve the corrosion resistance of low carbon steel following cladding with super duplex stainless steel using the laser powder bed fusion process.
The work shows that process parameters such as laser power, laser scan speed, hatch spacing, and powder layer thickness are critical for the best possible metallurgical bonding between the clad and the substrate. Clads produced at the lowest scan speeds showed comparable corrosion resistance to rolled and annealed super duplex stainless steel.
