The theme of this collection was 'Innovation and Development of Surface Engineering Towards a Conservation-Minded Society'; a timely reminder of the obligation of advanced technologies to commit to energy and resource saving and environmental protection. Surface engineering must play a more-and-more important role in energy-saving, materials-saving and environmental protection in the coming years obey the 4R (Reuse, Reduce, Recycle, Remanufacture) rule and contribute to development of the world economy.This collection of 201 peer-reviewed papers is grouped into seven sections: Thermal Spray Technology, Vapor Deposition Technologies, Electrodeposition and Electroless Deposition, Energetic Beams and Plasma Surface Treatments, Wear and Corrosion Behavior of Engineering Surfaces, Functional Films and Coatings, and Surface Machining and Mechanical Processing Technologies.This work therefore offers valuable insights into the scientific and technological achievements already made in this field and into the important progress still being made.
