However, its pure corrosion resistance at normal atmosphere is a matter of serious concern. I. INTRODUCTION usion welding based coating techniques generally suffers from dilution and thermal spraying results in mechanical bonding rather than metallurgical bonding. Friction surfacing is a relatively new technology which is capable of producing coatings with zero dilution and good metallurgical bonding. This is attained because no melting is involved in this process. Research so far has revealed that in friction surfacing the mechtrode force (F), mechtrode rotation speed (N) and substrate traverse speed (V x ) are of critical importance for the final quality of the coating and bond.  Development of a methodology for in-process precision measurement of temperature, torque, bonding time, spindle rotation speed and force.  Development of an empirical model involving process parameters V x , F, N and coating quality state variables C bs , Ct, Cw.

V.I.Vitanov, I.I.Voutchkov studied the three state variables, that reflect coating quality were considered as a subject for optimization and in this context a target for process parameter selection which are coating thickness, coating width, coating bond strength. Louda showed the examples of thin coatings application in automotive industry and commercial. Thereby gave economic, ecologic savings and maintain its environmental stewardship in the global market Tau V.R, Durodola B.M, Ajayi O.O, Loto C.A carried out the zinc deposition on mild steel with different parameters. Finally the coating surface examined with ion beam scanning electron microscope and x ray diffraction methods. III. COATING APPLICATIONS Use of thin coatings in automotive industry gives economic and ecological savings. This is evoking by reducing of weight of used construction elements and currently by increasing of their service life and with that connected elevating of nano materials manufacture qualities. 3.1 DECORATIVE COATINGS Product range of decorative coatings covers technologies for the entire spectrum of decorative and functional surface treatment for various materials including steel, aluminum and even plastics. At the present time are applications plastics as well as metal, from car wheels to bumpers and door handles to radiator grills. Decorative coatings can be made from:  Plating on Plastics  Copper  Precious metal Plastic and plastic composite materials continue to be popular because of the way they combine the advantages of both worlds. Plastics are light, corrosion-free and can be formed to virtually any shape. Even complex components can be cost effectively produced in volume. A metal surface gives plastics a high quality, decorative appearance. This is why the advantages of plating on plastics are being appreciated in more and more industries. The most popular type of decorative copper plating processes is Acid Copper. The high ductility of the acid coppers minimizes thermal expansion and flexing problems. Acid Copper is suitable for applications on zinc, brass and aluminium, bronze, steel, various other metal alloys, or most other commonly plated substrates. The copper deposit is easily buffed as is often required for intricate cast aluminium parts such as aluminium wheels. Acid Copper is versatile and very easy to operate. It is F
