| Abstract |
Laser cladding technology was developed as an alternative to hard chrome plating, which has a high environmental impact due to the use of hexavalent chromium. First, a basic evaluation of laser cladding was performed to determine the processing parameters. A prototype multi-use machine was then constructed integrating a laser cladding system and a cylindrical grinding machine, and the coating formation and grinding processes were evaluated. The results, we were able to form a high quality hard coating by laser cladding. Laser cladding coating was shown to be an alternative to hard chrome plating by confirming that the corrosion resistance, wear resistance, and adhesion strength were equivalent or superior to hard chrome plating. |
