Abstract

The automotive industry is one of the largest industrial segments in the world market. The exhaust system of motor vehicles is responsible for the emission and treatment of toxic gasses released by the engine. In this sense, the application of titanium on an AISI 1020 steel substrate was carried out by plasma deposition using a cathode cage. The aim of this research was to evaluate the application of this material in the exhaust system of motor vehicles. The samples were characterized by scanning electron microscopy (SEM), confocal microscopy (CM), microhardness tests and corrosion resistance tests. The samples exhibited a thin film with higher titanium content and hardness than the uncoated sample. The corrosion potential also increased and the current density was lower than the uncoated sample. The conclusion is that the deposition of thin titanium films on AISI 1020 steel with CCPD has the potential to produce thin films.

利用阴极笼等离子沉积技术在AISI 1020钢衬底上沉积ti基薄膜

汽车工业是世界市场上最大的工业部门之一。机动车的排气系统负责排放和处理发动机释放的有毒气体。在这种意义上，钛在aisi1020钢衬底上的应用是通过阴极笼等离子沉积进行的。本研究的目的是评价该材料在机动车排气系统中的应用。通过扫描电镜(SEM)、共聚焦显微镜(CM)、显微硬度测试和耐腐蚀测试对样品进行了表征。与未涂覆的样品相比，涂覆后的样品呈现出钛含量更高、硬度更高的薄膜。腐蚀电位升高，电流密度低于未涂覆样品。结果表明，用CCPD在AISI 1020钢表面沉积薄钛膜具有制备薄膜的潜力。
