Special Issue Information

Dear Colleagues,

Light metals are commonly used materials for lightweight structures of transportation equipment such as airplanes, automobiles, high-speed trains, and ships. Coating is the key to ensuring reliable service of lightweight structural components. The surface integrity, defects, and interface connection characteristics between the coating and the substrate will affect the surface properties and fatigue performance of the coated metallic materials. Exploring the internal relationship between coating preparation process–surface integrity and defect–performance is an important problem to be solved to promote the lightweight process of transportation equipment. The purpose of this issue is to publish the latest and original research results on lightweight materials with coatings. The methods of surface integrity and defect control and optimization of surface properties and fatigue performance of coated lightweight materials are presented. It provides the theoretical and methodological basis for solving the issues of the weight of transportation equipment.

This scope of this Special Issue will serve as a forum for papers in the following concepts:

  • The latest development of coating technology considering the surface properties and fatigue performance of lightweight materials;
  • The latest development of pre-treatment and post-treatment methods of coated lightweight materials;
  • Control mechanism of coating process on surface integrity and defects;
  • The influence mechanism of coating surface integrity, defects, and interface connection characteristics on surface properties and fatigue performance;
  • The constitutive relationship between coating and substrate;
  • Optimization method for coating preparation process;
  • Optimization methods for surface properties and fatigue performance of coated lightweight materials

Mg-Li alloy is widely used in aerospace and military equipment, but the research on its micromechanical mechanism is still insufficient. In this paper, molecular dynamics simulation is used to analyze the nano-indentation response and mechanical mechanism of single crystal Mg-Li. The deformation and hardness changes of Mg-Li under different loads were studied by load–displacement and hardness–depth curves. At the same time, the dislocation defects and equivalent stress are analyzed to reveal the dislocation formation and stress distribution in the process of deformation. Finally, under the condition of stress relaxation, the mechanical behavior of Mg-Li in the process of nano-indentation was revealed, and the deformation mechanism of Mg-Li alloy was studied.
