原位生成碳化钛对高锰钢堆焊层组织和性能的影响
In situ formation carbide high-mn steel hardfacing layer organization and performance influence
高锰钢作为高应力冲击载荷下的磨损器械材料被广泛应用于矿山机械中,但在低应力冲击载荷下,其优良的加工硬化能力得不到充分的发挥,因此,零部件在低应力载荷下磨损较为严重。本文通过在原有的D256焊条药皮的基础上加入钛铁、石墨等成分,通过电弧冶金反应生成碳化钛。利用金相分析、扫描电镜等测试与分析方法对研制的高锰钢堆焊焊条焊成的堆焊层的组织结构,硬度及耐磨性进行了研究,并与D256堆焊焊条进行了耐磨性对比,得出:自制焊条的硬度达到53HRC比D256焊条具有高的硬度,并且耐磨性有显著增加。
s high manganese steel under high stress impact load of wear equipment material is widely used in mining machinery, but in low stress under impact loading, the excellent work hardening ability get sufficient play, therefore, low stress loads in parts wear relatively serious. This article through the original D256 electrode medicine on the basis of titanium skin joined the composition such as iron, graphite, through the reactions that produce titanium carbide arc metallurgy. Use metallographic analysis and sem, testing and analysis method of high manganese steel developed facing electrode welded with the organizational structure of the hardfacing layer, hardness and wear resistance, and studied the D256 facing electrode wear also concludes that: homemade electrode D256 electrode 53HRC hardness of than with high hardness, and wear resistance have increased significantly.
