## Description

- description: A laser thermal processing technique was used to efficiently improve
    the corrosion resistance of 420J2 martensitic stainless steel. The top layer of
    the steel plate melted and immediately solidified by properly controlled laser
    irradiation. After the processing, the surfaces of the specimens were oxidized.
    The roughened oxidized layer that formed on the as-processed specimen was removed
    by grinding to expose the remelted layer. Potentiodynamic anodic polarization
    measurements confirmed that the remelted layer showed much better corrosion resistance.
    Furthermore, the hardness of the remelted layer increased to 700 HV. To evaluate
    the initial cell activity of the processed steel, osteoblast-like cell line (MC3T3-E1)
    was used. The initial proliferation of the cells was significantly improved on
    the laser-processed stainless steel. Therefore, laser thermal processing is a
    useful tool for developing novel materials with a combination of hardness, corrosion
    resistance, and cytocompatibility.
