MANUFACTURING AND ABRASIVE WEAR ANALYSIS OF MARTENSITIC STEELS REINFORCED WITH ZIRCONIUM OXIDE PARTICLES
Journal Title: The International Journal of Materials and Engineering Technology - Year 2019, Vol 2, Issue 1
Abstract
In mining industry and metallurgy, several wearing parts are subjected to the combined effect of abrasive wear and mechanical shocks that requires materials characterized by high hardness in surface and a better toughness in volume. In this present study, martensitic steel which is commonly used in industrial wearing parts is reinforced with zirconium oxides particles as ceramics inserts. Pellets of zirconium oxides that make up the ceramic inserts were prepared and, after casting of martensitic steel, samples were taken from the manufactured parts and characterized. Using ASTM G65 abrasive wear test apparatus, abrasive wear tests of the manufactured steel and, for comparison with other materials most currently used in mechanical industry, were conducted and wear surfaces were also characterized. It was shown that the manufactured steel with zirconium oxides allows improving wear resistance by approximately 44 %.
