Effect of Welding on Hardness and Deformation Behavior of Polypropylene by Scratch Test

Abstract:

Hot gas welding has been used in the process of polypropylene (PP) welding in many applications. It was appropriate for various multipart productions such as plastic constructions, automotive parts, tanks and pipeline. However, the surface properties of welded areas were varied particularly at each zone and thus affected numerous scratch resistances. The microstructure of scratch trace, hardness and scratch wear rate were studied by scanning electron microscope, hardness tester and scratch tester, respectively. From the results, it was found that the deformation of PP was induced with welding process. The scratch trace was showed that it related with decreasing of hardness properties.
