简介:采用CCDS2000型爆炸喷涂技术,在水泵和水轮机等流体机械常用不锈钢0Cr13Ni5Mo上制备WC-12Co涂层。采用金相显微镜、显微硬度仪、SEM、XRD、电子拉伸试验机、冲蚀试验机等测试分析手段和研究涂层的微观组织、显微硬度、孔隙率、结合强度、抗冲蚀性能等,并分析涂层的抗冲蚀机理。结果表明:制备的WC-12Co涂层的孔隙率为0.63%,硬度为1305.6HV0.2,涂层与基体的结合强度达到130MPa。此外涂层抗冲蚀性为基材G0Cr13Ni5Mo不锈钢的4.76倍。冲蚀后涂层内部裂纹主要以穿晶断裂、沿晶断裂形式扩展。因此利用爆炸喷涂制备WC-12Co涂层在高含沙水流的流体机械零部件上有广泛的应用前景。
简介:目的评价循环水除漆装置对苯、甲苯、二甲苯的净化效率和排放浓度,喷漆车间工作场所空气质量是否达标。方法分别在净化前后的管道内端面设置采样点,采用净化前后同步等时采样,连续采取3个工作日的浓度,对检测结果进行分析。结果净化后苯、甲苯、二甲苯的平均排放浓度分别为0.72、3.04、36.4mg/m3,平均净化效率分别为64.24%、82.46%和60.91%;喷漆车间内空气中苯、甲苯,二甲苯浓度均符合职业卫生接触限值;喷漆房二甲苯CSTEL、CTWA浓度均超出标准。结论该净化装置对降低工作场所空气中苯、甲苯、二甲苯的浓度有较好的效果。但苯类等有机溶剂类很难通过简单的喷淋吸收达到高净化效果,在循环水中加上能够吸附苯类的设施和吸附过程,可望提高其净化效率。
