npj Materials Degradation publishes high-quality papers reporting significant advances in basic and applied research on the degradation of metallic and non-metallic materials. We broadly define 'materials degradation' as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. Topics of interest to the journal include - though are not limited to - the following: corrosion of metals; long-term stability and durability of glasses, minerals and cements; weathering and light/heat induced damage to polymers; degradation of ceramics by extreme temperatures/stresses; irradiation-induced damage to metals and ceramics etc. Representative journal scope includes: Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli: chemical, heat, light, mechanical stress, irradiation etc., and combinations of these. Computational and experimental studies of degradation mechanisms and kinetics. Characterization of degradation, in terms of changes to structure and material properties, by traditional and emerging techniques. New approaches and technologies for enhancing resistance to degradation, ranging from materials design to coatings. Inspection and monitoring techniques for materials in-service, such as sensing technologies. As well as publishing original research papers, npj Materials Degradation also welcomes the submission of critical Reviews, thought-provoking Perspectives, and Brief Communications. We are additionally interested in discussion pieces from industry that address challenges faced in the application of materials in demanding environments. .
