在替代钴基合金堆焊材料的试验研究中，采用MMA、TIG和等离子转移弧（PTA）焊接工艺对Fe 52和AISI 316L钢的1、2和3层堆焊试样进行了堆焊。使用以下填充金属：（Co-Cr-W-C）合金4（Fe-Cr-Mo-V）合金2（Ni-Cr-B-Si）合金5（Ni-Cr-C-Mo）合金3（Ni-Cr-C-W）合金6（Fe-Cr-Mo-Mn）堆焊试样进行了高温硬度、冲击强度、滑动磨损、磨粒磨损、硬度计分析、腐蚀试验、化学分析、金相分析、显微硬度、耐磨性等试验。和金相试验。结果表明，合金1（被选为参考合金）具有最好的表面硬化性质和总体性能，并且存在有效的替代合金，例如5号、3号和4号，然而这表明它们在表面硬化的执行中需要更大的小心。
Abstract In the course of experimental research on hardfacing materials to be used as a substitute for Co-based alloys MMA, TIG and plasma transferred arc (PTA) welding processes were used for hardfacing 1, 2 and 3-layer specimens of Fe 52 and AISI 316L steels. The following filler metals were used: Alloy 1 (Co-Cr-W-C) Alloy 4 (Fe-Cr-Mo-V) Alloy 2 (Ni-Cr-B-Si) Alloy 5 (Ni-Cr-C-Mo) Alloy 3 (Ni-Cr-C-W) Alloy 6 (Fe-Cr-Mo-Mn) Testpieces were taken from the hardfaced specimens for the following tests: high temperature hardness, impact strength, sliding wear, abrasive wear; dilatometric analysis; corrosion tests; chemical analysis; and metallographic tests. The results show alloy 1 - chosen as the reference alloy - to have the best hardfacing properties and overall performance, and the existence of valid alternative alloys such as No. 5, 3 and 4, which nevertheless showed that they required greater care in the execution of the hardfacing.
