A review of the important trends for improving corrosion, electrical insulation, wear resistance, superficial or rolling-contact fatigue behavior (for application at room T° as at high T°) but also to reduce as well the frictional losses in accordance to the principles of the "Industry 4.0" will be presented. A full review of the existing "high tech" coatings helping for solving the precedent issues will also be exposed.
