摘要
为分析体育器械用镁合金材料的激光表面改性处理效果,对镁合金材料预处理,确定激光熔凝处理工艺,计算镁合金材料表面的硬度、耐磨性和耐腐蚀性,并建立研究期内检测数据的数据库,使用SPSS17.0软件统计分析数据结果。结果显示,当激光熔凝改性处理采用的激光功率为3 kW时,改性镁合金材料表面的硬度、耐磨性和耐腐蚀性效果提升最为明显。试验表明,激光熔凝处理会加强镁合金材料表面的硬质含量、强化沉淀作用,细化α-Mg晶粒,减小β相之间的间距,形成更致密的Al_(2)O_(3)氧化膜,促使镁合金材料中的杂质元素分布更为均匀,从而提高镁合金材料表面的物理、化学和力学性能,提升镁合金材料的硬度、耐腐蚀性及耐磨性。
In order to analyze the effect of laser surface modification treatment of magnesium alloy materials for sports equipment,magnesium alloy materials were preprocessed,and the laser melting treatment process was determined.Moreover,the hardness,wear resistance and corrosion resistance of the surface of magnesium alloy materials were calculated,and the database of the detection data in research period was developed,which was analyzed by using SPSS17.0 software.Results show that when the laser power used in the laser melting modification treatment is 3 kW,the hardness,wear resistance and corrosion resistance of the modified magnesium alloy surface are improved most obviously.Experiments show that laser melting treatment can enhance the hard content of the surface of magnesium alloy materials,strengthen precipitation,refineα-Mg grains,reduce the spacing betweenβphases,and form a denser Al_(2)O_(3)oxide film.These results make the distribution of impurity elements in the magnesium alloys more uniform,thereby improving the physical,chemical and mechanical properties of the surface of the magnesium alloy material,and improving the hardness,corrosion resistance and wear resistance of the magnesium alloy material.
