In this research work, the sustainable temperature-dependent coating was developed with the use of agriculture waste with the aid of HVOF technology. The various characterization and testing techniques such as Vickers micro-hardness tester, high-temperature tribometer, and FESEM-EDS are practiced for evaluating and examine the microstructures, surface morphology, wear, corrosion, and mechanical properties. The high-temperature tribometer was employed for evaluating the tribological performance of the developed coating and showed the range of value 0.28–0.43 of COF, whereas wear value was received in the range of 42–145 µm at the followings tested conditions of temperature varies from 5 to 200 °C, load (30–60 N) and sliding velocity (0.1–0.4 m/s) respectively. The result obtained from the tribological test shown increment in micro-hardness i.e. 75%, COF decreases 34.88%, and at a temperature of 200 °C, the value of wear is reduced to 71% during the wear test at a SV of 0.4 m/s and applied load of 60 N. |
