| Abstract | The effect comparison of applying Friction Stir Processing (FSP) with two different Nanoparticles; CNT (Carbon Nano Tubes) and ZrO2, on St37 steel Micro-hardness changes has been investigated. In FSP fabrication method, the rotational speed was 900 rpm and the traverse speed was 100 mm/min. The obtained Micro-hardness results from both Nano-particles have been compared with the one in Base Metal (BM). Both Nanoparticles (CNT and ZrO2) were tested in the same total dominant condition. It is note-able that the nugget zones' Micro-hardness of both FSP Nano-coated samples have experienced a great promotion in comparison to the one in BM. However, the CNT one allocates a greater promotion slope to itself. By comparing the three fabrication zone products (Nugget Zone, TMAZ, HAZ); it will be understood that CNT sample experiences a greater difference between three fabrication zones rather than the ZrO2 ones. |
