Tribological behavior of HVOF based composite coatings for wear resistance applications

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 mm at the followings tested conditions of temperature varies from 5 to 200 degrees 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 degrees 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.
