| 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.
