Title:
WEAR-RESISTANT MATERIAL, WEAR-RESISTANT IMPELLER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/049972
Kind Code:
A1
Abstract:
A wear-resistant material is prepared by Ni-base alloy powder and additives, and the Ni-base alloy powder comprises the following components in percent by mass: 0.1% to 1.1% of C, 0.5% to 6.0% of Si, 2.5% to 15.0% of Fe, 0.2% to 5.0% of B, 6.0% to 26.0% of CrB2, and the balance Ni. Because CrB2 and WC are added, the wear resistance of the wear-resistant material is improved. The hardness of the wear-resistant material can reach 70 to 80 HRC. A preparation method for a wear-resistant impeller is also provided. The wear-resistant impeller employs the wear-resistant material as a hard surface layer, so the wear resistance of the impeller is improved.
