Beschreibung
Zusammenfassung:	The invention discloses a high corrosion-resistant powder material and a preparation method and application thereof. The powder material comprises the following components in percentage by mass: B: 0.5-2.0%, Ni: 1.0-3.0%, Cr: 12-20%, Si: less than 2.0%, Mo: less than 2.5%, and the balance Fe. The preparation method comprises the following steps: 1, smelting an alloy; 2, atomizing metal; and 3, screening powder. The powder material can be used for preparing a high corrosion-resistant wear-resistant coating on the surface of alloy steel by a laser cladding method, the hardness of the coating canreach 53-58 HRC, and the neutral salt spray test is more than 1000 hours. 本发明公开一种高耐蚀粉末材料及其制备方法及应用，按照质量百分比计算，所述粉末材料包括如下组分：B：0.5~2.0%，Ni：1.0~3.0%，Cr：12~20%，Si＜2.0%，Mo＜2.5%，余量为Fe；所述制备方法包括：步骤一合金熔炼，步骤二金属雾化，步骤三粉末筛分；所述的粉末材料能用激光熔覆方法在合金钢表面制备高耐蚀耐磨涂层，涂层硬度可达53~58HRC，中性盐雾试验＞1000小时。
