Abstract
A wear resistant material is manufactured from a Ni-based alloy powder and an additive. The Ni-based alloy powder includes the following components in mass fraction: C: 0.1˜1.1%, Si: 0.5˜6.0%, Fe: 2.5˜15.0%, B: 0.2˜5.0%, CrB2: 6.0˜26.0%, and the balance of Ni. The Ni-based alloy powder is employed as the main component and CrB2 and WC are added, thus improving the wear resistance of the wear resistant material. Experimental data show that, the wear resistant material provided in the present disclosure has the hardness up to 70˜80 HRC and excellent wear resistance. A wear resistant impeller can be manufactured from the wear resistant material.
