A Review on the Enhancement of Mechanical and Tribological Properties of MCrAlY Coatings Reinforced by Dispersed Micro and Nanoparticles

The application of metal-matrix composite coatings for protecting and improving the service life sliding components has demonstrated to have potential meeting requirements a diverse range engineering industries. Recently, significant body research been devoted studying mechanical tribological performance dispersion-strengthened MCrAlY coatings. These belong class emerging wear-resistant materials, offering improved properties being considered as promising candidates protection structural materials exposed damage, especially at elevated temperature regimes. This paper attempts comprehensively review different reinforcements used in processing MCrAlY-based alloys how they influence corresponding Furthermore, major fabrication techniques together with their benefits challenges are also reviewed. Discussion on failure mechanisms these well main determining factors included. In addition, comprehensive survey studies investigations recent times summarized elaborated further substantiate review.
