Abstract
Reusing and organizing industrial solid waste not only tackles the problem of rising environmental contamination but also lowers landfill space. Furthermore, repurposing these wastes for certain possible uses lowers material costs and production costs. Consequently, the research focuses on the repurposing of marble dust, a by-product of ornamental stone processing, for use as a coating material on metal substrates. A well-designed high-velocity oxy-fuel spray coating equipment is used to deposit the material. In accordance with ASTM G 99-05, high-temperature sliding wear tests are performed on the depositions of coatings using a tribometer, incorporating Taguchi’s L16 orthogonal array. Control variables with a substantial influence on wear loss are discovered, and an ideal factor setting is determined based on the least wear loss. The morphologies of worn surfaces are studied to identify probable wear processes. Based on the outcome of parametric analysis, experiments are conducted using a diverse set of recognized significant control factors, while maintaining consistency in the other variables, to enhance the accuracy of assessing their individual impacts on the specific wear rate.
