Experiments were carried out with different process parameters to investigate the effects of used parameters on corrosion resistance of TiN coatings obtained. In experiments, TiN imitation gold decoration coatings were prepared on 1Cr13 pen-point and brass chromium plating pen-coil by multi-arc ion plating method. The phase composition of TiN coatings was measured by x-ray diffraction. The corrosion resistance of TiN coatings was tested by salt-mist and artificial-sweat experiments. The relationship between corrosion resistance of coatings and process parameters were analyzed. Therefore, the optimum process parameters were achieved suitable for plating coatings on substrates of 1Cr13 pen-point and brass chromium plating pen-coil with good imitation gold. Imitation gold plating layers obtained have good gloss, corrosion resistance, high hardness, wear resistance, and easy to maintain. The results showed that the corrosion resistance of coatings is more easily influenced by changes of PN2 and Vbom than that of matrix-bias voltage. The TiN coatings are of resistant to corrosion no matter they are in single or multi phase structure. The optimum parameters of achieving good corrosion resistance of TiN coatings are PN2=0.48Pa, Vbom=400V，bias=-20V. Under the optimum conditions, the obtained surface corrosion resistance state of the coatings can reach at least eight grades, even above ten grades.

Plasma Electrolytic

Plasma electrolytic saturation (PES) technique which holds the advantages of short treating time and limited heating influence and immediate quenching effect is conducted under high voltage power supply in some electrolyte has been extensively applied to enhance the surface performance of metallic materials. Steel is widely used in various fields thanks to its promising merits of easy workability, plasticity, toughness and weldability. It accounts for a large proportion in the application scope of the metal materials. Steel surfaces with good corrosion resistance, promising wear resistance and high hardness would be obtained by PES. Meanwhile, uniformed coatings can be formed without special requirements for substrate geometries using the PES. This paper first presents a brief introduction of the technological principle of PES. The status on studies and applications of PES for improving surface performance of steels has been reviewed.

Technological Limitations

This article presents the brief overview of fairly recent and eco-friendly micro arc oxidation (MAO) coating technology. The weight-cost-performance benefits in general raised the interest to utilize lightweight materials, especially the aluminum and its alloys. Despite numerous engineering advantages, the aluminum alloys themselves do not possess suitable tribology and corrosion resistance. Therefore, improvements in surface properties are essential to enable developing potential industrial applications. For improving wear and corrosion resistance of Al alloys, the most demanding surface properties are high hardness and chemical inertness. The technical and technological limitations associated with traditional anodizing and hard anodizing processes have been the strongest driving force behind the development of new MAO technology. While presenting the key technological elements associated with the MAO process, the basic mechanism of coating formation and its phase gradient nature is presented. Influence of various process parameters including the electrolyte composition has been discussed. The typical microstructural features and distribution of α- and γ-Al2O3 phases across the coating thickness as a key strategy to form dense coatings with required mechanical, tribological, and corrosion properties which are vital to meet potential application demands are briefly illustrated.
