Zusammenfassung:	The invention relates to a cobalt-based plasma powder surfacing material as well as a preparation method and application thereof. According to the cobalt-based plasma powder surfacing material, sintered WC-Co hard alloy particles with the particle sizes being 60-100 meshes are used as a wear-resisting phase, cobalt-based alloy powder with the particle sizes being 100-325 meshes is used as a binding phase, the weight percentage of the wear-resisting phase is 20%-60%, and the weight percentage of the binding phase is 40%-80%. The cobalt-based plasma powder surfacing material has perfect combination of wear resistance and impact resistance, is particularly suitable for surface strengthening of sealed bearings with particularly-high wear resistance requirements, and can also be used for improving the wear resistance in an open environment with the particularly-high load. 本发明涉及一种钴基等离子粉末堆焊材料及其制备方法和应用，该钴基等离子粉末堆焊材料以粒度60～100目的烧结WC-Co硬质合金颗粒为耐磨相、以粒度100～325目的钴基合金粉为粘结相，其中，耐磨相所占的重量百分比为20～60％，粘结相所占的重量百分比为40～80％。本发明提供的钴基等离子粉
