Abstract

Co-Cr-Mo alloy samples were deposited using arc welding process with optimum parameters of deposition. The samples were tested for their hardness, XRF, wear resistance and microstructures. The results were compared with the laser deposited samples and cast samples from literature. The experimental results revealed that the hardness of the weld deposits was inferior to as-cast samples as well as the laser deposited samples. But the wear resistance of the weld deposited samples was compatible with laser deposited samples. Metal to metal contact Pin on Disc wear resistance test was conducted. The XRF results were in agreement with results of as-cast samples. Scanning electron microscopy was used for microstructure analysis. Thorough investigation was made to compare the microstructures of the weld deposits with laser deposited and as-cast Co-Cr-Mo alloy samples.
