Introduction

Zirconium-based conversion coating, as a suitable alternative for common phosphate and chromate coatings, are widely applied on metallic surfaces to promote the paint adhesion and improve the corrosion performance. These coatings are based on the eco-friendly compounds; furthermore, the main advantage of these coatings is no need for thermal energy which consequently leads to cost reduction.

Introduction

Wear- and corrosion-resistant super-hard nanolayer and nanocomposite coatings are widely applied onto the surface of the turbine and compressor blades in the oil, gas and aerospace industries as an alternative for the conventional coatings. It is worth mentioning that the deposition of above-mentioned coatings is performed by using a Hybrid PVD system which operates based on both cathodic arc and sputtering processes.
