| Abstract [eng] |
In this research work the welded surface suing submerged arc weld overlay cladding technique is investigated to determine which sample mixture has higher hardness, higher wear resistance at various conditions. The materials used for surface layering of base metal is of different waste material powders collected for the research purpose and these powders are mixed in various proportions to prepare five samples. Samples are tested for hardness after welding using Rockwell hardness test and then the samples are cut into three different parts for further examination. Microstructure examination is done is this research using microscope that has maximum magnification range of 250x. Wear test is performed using the wear testing machine for which the samples are cut into 6mm length small piece These three parts are used as each for analyzing the hardness, inspecting the microstructure and calculating the wear resistance. Tempering of the samples are done to investigate whether at which tempering temperature the efficiency of the samples are increasing and also to evaluate the value it is increasing. The results obtained from these tests are studied, analyzed and investigated in this work and the usefulness of the waste material powder are assessed. |
