Wear Resistance Property of Hardfacing Weld Overlays Containing Metal Carbides

High-chromium white iron based weld overlay materials containing metal carbides were deposited, and the wear performances were evaluated using a dry sand/rubber wheel test according to American Society for Testing and Materials G65-04 standard. The test results demonstrated that the weld overlay mat...
