Abstract

Abstract In this article, the effect of shielding gas combinations on gas tungsten arc-welded dissimilar AISI 310 steel and AISI 2205 steel joints was investigated. Two gases such as nitrogen and carbon dioxide were substituted in argon shielding gas and its corresponding improvement in the mechanical, microstructural, machining, and wear aspects of the dissimilar AISI 310–AISI 2205 joints was studied. Weld bead studies, tensile, and weld region microhardness were conducted. X-ray diffraction studies revealed joint intermetallics, and microstructural evaluation was conducted. Machining studies were conducted using drilling experiments. Using local analysis and global analysis, the cutting force variations in the feed direction and cutting direction were studied. Wear tests revealed that the variations in traction force, specific wear rate, coefficient of friction and tribo wear mass loss were studied. A considerable improvement in wear characteristics of AISI 310–AISI 2205 joints was observed by substituting CO2 and N in shielding gas.

保护气体对AISI 310–AISI 2205异种不锈钢接头加工和磨损方面的影响

摘要本文研究了不同保护气体组合对不同AISI 310钢和AISI 2205钢钨气弧焊接头的影响。采用氮气和二氧化碳两种气体替代氩气，对不同类型AISI 310-AISI 2205接头的力学性能、显微组织、加工性能和磨损性能进行了研究。焊接头研究，拉伸和焊缝区域显微硬度进行了。x射线衍射研究显示接头金属间化合物，并进行了显微组织评价。加工研究是通过钻孔实验进行的。采用局部分析和全局分析的方法，研究了进给方向和切削方向切削力的变化规律。通过磨损试验，研究了牵引力、比磨损率、摩擦系数和摩擦磨损质量损失的变化规律。在保护气体中加入CO2和N可显著改善AISI 310-AISI 2205接头的磨损特性。

期刊介绍： High Temperature Materials and Processes offers an international publication forum for new ideas, insights and results related to high-temperature materials and processes in science and technology. The journal publishes original research papers and short communications addressing topics at the forefront of high-temperature materials research including processing of various materials at high temperatures. Occasionally, reviews of a specific topic are included. The journal also publishes special issues featuring ongoing research programs as well as symposia of high-temperature materials and processes, and other related research activities. Emphasis is placed on the multi-disciplinary nature of high-temperature materials and processes for various materials in a variety of states. Such a nature of the journal will help readers who wish to become acquainted with related subjects by obtaining information of various aspects of high-temperature materials research. The increasing spread of information on these subjects will also help to shed light on relevant topics of high-temperature materials and processes outside of readers’ own core specialties.
