Abstract
Degradation of metal is a severe problem in the world today. Understanding the behaviour of metals and alloys has been an object of investigation for long, as it is not possible for a single material to have different properties to meet the demand of today’s industry. So, a composite system of a base material is required to provide the necessary mechanical properties and a protective surface layer which immune the substrate from hot corrosion, erosion and wear. Carbide based coatings have reported to be used for combating erosion and corrosion problems. In this article a brief review of the performance of carbide based coatings has been made to understand their hot corrosion and erosion behaviour.
