Tooling and die failure is a prime concern for hot forging industry for survival in the competitive globe. Different methods are employed to protect the tools/dies from degradation. Thermal spraying is one of the most effective methods to protect the material from wear, thermal fatigue and plastic deformation due to adverse environments during hot forging process, thus increasing the life of material in use. A coating is a covering process that is applied to the surface of a material which is referred to as the substrate. The coating itself is either completely covered through the whole surface or the particular parts of the substrate. Different coatings are used to achieve the desired properties. In this process, relatively thick metallic, polymer, ceramic and composite coatings is deposited. The optimum coating process is selected on the basis of desired coating properties. Coating material is either in the form of wire, powder, rod, cord or molten-bath form. The procedure may be manual, mechanized or fully automated. This paper attempts to define some of the current important issues and research priorities in the plasma spray field.
