针对高应力磨粒磨损工况条件研制的中铬ＣＣｒＭｏ系奥氏体合金堆焊材料ＦＡＷ焊条，具有焊接工艺性好、堆焊金属抗裂性好和加工硬化率高的特点，是替代奥氏体锰钢的理想焊接材料。通过对该材料的硬化和磨损性能及其机理的试验研究，探讨了合金的冷作硬化及冲击磨损的一般规律。硬化机制以形变强化与碳化物析出强化为主，磨损形式以塑性凿削式去除为主。 For high stress abrasive wear condition conditions developed in the medium chromium C Cr Mo alloy austenitic alloy surfacing material FAW electrode with good welding technology, good surfacing metal crack resistance and high processing and hardening rate characteristics, Is the ideal alternative to austenitic manganese steel welding materials. Through the experimental study on the hardening and wear properties of the material and its mechanism, the general rules of cold work hardening and impact wear of the alloy were discussed. Hardening mechanism to strengthen the deformation and carbide precipitation-based, wear form to plastic chisel-based removal.
