Abstract

The main focus of this work is enhancing the steel rollers wear resistance which is used in mining industry conveyor systems. Wear and efficiency of steel conveyor system is affected by the presence of sand, dust and grit (abrasive particles) and by the continuous contact between metal surface with steel roller. To overcome the above issue, application of molybdenum powder coating for the steel is suggested using plasma thermal spray coating. As per the ASTM (American Society for Testing and Materials) standards the experiments are conducted and the performance enhancement analyzed for the coated samples by comparing with uncoated samples. ASTM G65 is a test method developed by ASTM International to evaluate the abrasive wear resistance of materials using a dry sand/rubber wheel abrasion test. This test method is commonly used to assess the durability and wear performance of various materials, coatings, and surface treatments. SEM (Scanning Electron Microscope), EDAX (Energy Dispersive X-Ray analysis) and hardness tests are performed to measure the wear resistance and wear surface properties. It is proven that the molybdenum coating plays very important role in improving the three-body wear resistance of steel conveyor rollers. SEM analysis confirmed a smooth and well-adhered coating, while EDAX revealed the presence of molybdenum on the coated surface. Hardness tests indicates a notable increase in hardness, further supporting the enhanced wear resistance. This research highlights the potential of molybdenum powder coatings to enhance the durability and lifespan of steel rollers in conveyor systems operating in harsh environments. The findings contribute to the development of effective strategies for reducing wear and optimizing the performance of mining and construction equipment.
