Most often breakage in heat-and-power facilities is caused by decomposition of heating elements while in process. The reason of it is a thick layer of boiler scale on their surface caused by hardness salts and ferric carbonates in industrial water, as well as by roughness of the surface of the heater. The quality of the surface is improved by polishing and covering it with a layer of nickel. The above-mentioned processes could be replaced by covering the surface with a composite electrochemical coating (CEC nickel-fluorocarbon) using fluorocarbon production residue which contains a mixture of fluorocarbon and carbon black. Estimate of the parameters of the process of getting CEC nickel-CF x showed that nickel current output does not depend on presence of a dispersion phase (CF x ) in conditions of high current density. Throwing power is even, so that it is possible to get uniform nickel coatings and CEC nickel-CF x . It was stated that the physical characteristics, as well as anti-scaling and anti-corrosion characteristics of CEC nickel-CF x are higher than those of nickel coating. CEC nickel-CF x is recommended for using in heat-and-power equipment.
