, and the accumulation of defects will occur during the second forming process. The self-healing phenomenon of hole defects in SLM process has also been proved by ZHOU et al [27], that is, local hole defects heal in the subsequent forming process to form closed pore defects, which will not expand indefinitely, as shown in Figure 6(a). The self-healing mechanism has obviously become a secondary factor after......
, additional research focused on preparing multi-layer coating with excellent self-healing ability is necessary. Fig.6 Surface morphologies of coated samples after oxidation at 1 623 K for 10 h: (a) SiC... to the quick cooling of the modified sample from 1 623 K to room temperature in the oxidation test, penetrating cracks were inevitably formed in the coating. Though these penetrable cracks can be self-sealed......

that can be self-healing if damaged. However, at 400-600 ℃ MoSi2 suffers from catastrophic oxidation sometimes referred to as pesting[1]. There are several investigations that have dealt with the so......
applications[1]. In addition, magnesium cannot form a self-healing passive surface contrast to aluminum and titanium, because there is a misfit between the hydroxide lattice in the surface region and the lattice of the bulk material. Therefore, the magnesium hydroxide film is loose and the layer is undermined by corrosion process[2]. Because aluminum and its alloy have the ability to self-repair......
