通过X射线衍射仪(XRD)、扫描电镜(SEM)、透射电镜(TEM)和电化学工作站,研究了淬火+回火处理后SUS420J2塑料模具钢的物相组成、微观形貌和耐蚀性。结果表明:SUS420J2塑料模具钢中M23C6的存在与淬火和回火温度密切相关,较低温度(980℃和1 030℃)淬火后试样中会有部分M23C6碳化物残留,而650℃高温回火后试样会析出大量尺寸细小的M23C6碳化物。当淬火温度为1 030℃时,300℃回火后试样中可见未溶微米级M23C6碳化物,500℃回火后试样中出现较多的M23C6碳化物(粒径小于0.1μm),650℃回火后试样中可见弥散分布的M23C6碳化物(粒径约0.5μm)。相较于500℃回火后试样,300℃和650℃回火后试样表面钝化膜对基体的保护性能更好,试样耐蚀性更好;300℃回火后试样的耐点蚀性能优于650℃回火后试样的,500℃回火后试样的耐点蚀性能较差,这主要与热处理过程中富Cr的M23C6碳化物的尺寸与存在形式有关。

由于线胀系数差异大,Cf/Si C复合材料与TC4钛合金钎焊接头容易形成较大的内应力而开裂失效。为了进一步提高接头强度,应用激光毛化工艺在Cf/Si C表面烧蚀出微孔,采用银基钎料对Cf/Si C与TC4进行钎焊。焊后对接头力学性能进行测试,对接头界面及断口显微组织进行观察。结果表明:焊前对Cf/Si C表面进行激光毛化处理,钎料能够填充微孔并形成良好的钎焊界面,能够提高Cf/Si C与TC4钎焊接头的剪切强度。
