HARDFACING PROCESS AND PARTS PRODUCED THEREBY |
摘要 |
A hardfacing process includes depositing a clad layer having a thickness greater than about 1 mm (0.04 in) on a surface of the component by arc welding, and creating a heat affected zone directly below the clad layer due to the depositing. The heat affected zone may be a region of the component where a lowest hardness is more than 40% lower than a base hardness of the component below the heat affected zone. The method may also include heat treating the component after the deposition such that the lowest hardness in the heat affected zone is restored to within about 15% of the base hardness of the component. |
