Investigating surface morphology, microstructural characteristics, and scratch resistance in novel nano-composites enhanced by innovative thermal spray technique

Researchers have been investigating unique methods to produce novel nano-composites in response to a growing need for sophisticated materials with higher surface characteristics, improved microstructures, and increased scratch resistance. The development of high-velocity air-fuel coating technology has shown promise in the production of high-quality coatings with distinctive material properties. Examining the surface morphology, microstructural characteristics, and scratch resistance of nano-composites improved by HVAF coating is the primary objective of this investigation. The creation of nano-composites is initiated by considering the particle size and shape. The HVAF coating procedure is done on mild steel surfaces using nanocomposite materials, ensuring a strong bond between the coating and the substrate and enhancing mechanical performance. Scanning electron microscopy (SEM), among other sophisticated microscopy methods, is used to extensively examine the surface morphology and microstructural characteristics of the coated substrates. Standardized scratch tests that measure scratch resistance are also used to evaluate the coatings' resilience to mechanical stress. The outcomes of these experiments provide important information on the efficiency of HVAF-enhanced nano-composites in enhancing surface properties and scratch resistance. These advanced materials have the potential to find applications across various industries, particularly wherein performance and durability are paramount, such as aerospace and automotive.
