Surface Engineering and Protective Coating towards Biocompatible Applications

Surface integrity plays an important role in mitigating the degradation and failure of structural metal alloy components, especially in corrosion and/or erosion environments. This collection specializes in new developments of materials and technologies within the scope of surface engineering and protective coating towards biocompatible applications.

Ever-growing additive manufacturing (AM) of structural metal alloy components are pushing the requirement for surface finishing at an unprecedent pace. The rough surface of AM components adversely influences their fatigue life while dross particles breakoff from AM components may cause local contaminations of their serving environment. These intrinsic characters, together with lack-of-fusion defects, bring up a great challenge for AM components to serve, e.g., biomedical implants, in corrosion and/or erosion environments. On the other hand, one of the most important advantages of AM is rapid manufacturing of customized structural components with complex geometries. Traditional methods may lose their efficiencies or even fail in surface finishing of such AM components with complex surface geometries. In this light, material and technology development for surface finishing of AM components has been attracting increasing research interest worldwide, driven not only by the technical challenges but also by the industrial requirements. Surface engineering and protective coating are basically two dominant technicial routes for surface finsihing of AM components. Understanding the relationship among the process, micronstructure, and performance plays a key role in both surface engineering and protective coating. Theoretical modlling and simulations, as well as their assistance by merchine learning and artificial intenligence, have been emerging as a strategic tool for accelerating the material selection and process design/optimization.
