| Abstract: | The influence of compaction and surfacing technology on the performance of surfacing layer was studied by depositing mixed iron alloy powder compacts on Q235 steel plate by argon arc welding.The results show that when the total mass of the fixed briquette powder is 16 g,the content of ferronickel is 0.64 g,and the welding current is 180 A,the hardness of the surfacing layer is the highest,reaching HRC48.9,and the wear resistance is the highest, the relative wear is 0.013 4 g/(cm^2·min). |
