Provided is a nickel-based composite coating, method for producing the same and use thereof. A powder mixture is coated on the surface of a substrate to obtain a nickel-based composite coating, wherein the powder mixture comprises nickel-chromium-boron-silicon powders and barium titanate powders. The barium titanate powders are added to the nickel-based powders as a second phase to form BaTiO.sub.3—NiCrBSi metal-based ceramic composite coating. The nickel-based barium titanate composite coating has an excellent damping shock absorbing performance and gives the substrate strength as well. Comparing with the conventional coating materials, the coating obtained by the present disclosure through plasma cladding technique not only bonds with the substrate in a metallurgic way, but also has a small heat affected zone, specifically, an excellent damping shock absorbing performance. In embodiments of the present disclosure, vibration and noise generated by the cylinder head is reduced 20% by using the shock absorbing cladding coating.
