Abstract Degradation of a material due to the chemical/electrochemical and/or frictional interaction with the surroundings initiates at the surface because of the external stresses and frequent environmental attacks. The surface properties like hardness, wear resistance and corrosion resistance can be improved by means of composite coating. Recently Nickel based composite coating has found a new horizon because of excellent wear and corrosion resistance and high hardness. In this article, the Ni based metal matrix composite coating by various techniques are reviewed. Composition, process parameters, subsequent mechanical properties as well as microstructures and their effects are briefly tailored. Finally, new directions for future work on this technology are suggested. Graphic Abstract

1 Introduction In any engineering part, first the surfaces are subjected to the frictional, thermal, mechanical, chemical as well as electrochemical interaction which results in damage to the components in the industry. This damage cannot be recovered if the tribological and corrosion phenomenon is not controlled properly. By the application of appropriate surface technology the damage can be prevented or at least delayed. So, surface coating technology is most efficiently used to increase hardness, wear resistance, corrosion resistance and resistance at high temperature without altering the properties of substrate [1]. Modern researchers have adopted a new form of coating which is called composite coating. Normally the composite material includes different types based on matrix materials such as metal matrix composites, ceramic matrix composites, polymer matrix composites and carbon matrix composites [2]. Among them metal matrix composite coating is popularly used in the industry for its versatileness.
1.1 Metal Matrix Composite Coating MMC coating combining high hardness and strength of ceramic phase and sound toughness of the matrix is widely used for repairing of surface and strengthening of engineering metal components. There are two techniques for the addition of reinforcing particle. External addition or ex situ have its inherent problem of bonding between particles and matrix due to poor wetting properties between ceramic and metallic phase. Whereas in the in situ synthesis, the ceramic reinforcing phase in the coating is formed by chemical reaction among elements of precursor material at a very high temperature, followed by in situ nucleation and growth. As a result, those hard particles are thermodynamically stable and finer than that of hard particles which are added externally. Composite coating of var
