耐腐蚀焊条及其制备方法
摘要：
本发明涉及具有耐腐蚀性能的焊条，属于焊接材料领域。焊条包括焊芯和药皮，所述药皮由下述重量百分比的组分组成：碳化钨2～10％、碳化硼或氮化硼2～8％、镍粉2～10％、铜0.30～0.85％、稀土0.2～4.60％、锰氮合金和/或钒氮合金任意比例0.20～2.80％、钼铁0.6～3.2％、大理石25～38％、钛白粉2～8％、萤石1～6％、锰铁3～8％、钒铁0.35～4％、铌铁或钛铁0.35～4％、铬铁余量；其中，锰铁为低碳锰铁或微碳锰铁；铬铁为低碳铬铁或微碳铬铁。本发明焊条具有耐蚀耐磨的性能，且焊条的堆焊层硬度HRC一般大于55，同时焊接性能好，适用母材范围广，成本较低。
摘要（英）：

The present invention belongs to the field of welding material technology, and is especially one kind of anticorrosive welding rod. The welding rod includes one core wire and one welding rod coating comprising tungsten carbide 2-10 wt%, boron carbide or boron nitride 2-8 wt%, nickel powder 2-10 wt%, copper 0.30-0.85 wt%, RE elements 0.2-4.60 wt%, Mn-N alloy and/or V-N alloy in any ratio 0.20-2.80 wt%, ferromolybdenum 0.6-3.2 wt%, marble 25-38 wt%, titanium white powder 2-8 wt%, fluorite 1-6 wt%, low carbon ferromanganese 3-8 wt%, ferrovanadium 0.35-4 wt%, ferroniobium or ferrotitanium 0.35-4 wt%, and low carbon ferrochrome for the rest. The welding rod has high corrosion resistance, high wear resistance, good welding performance and other advantages.
