涂层材料与基材之间的润湿能力决定了激光涂层组织的质量,尤其是预置涂层的激光涂复。其润湿能力强的材料在激光涂复后能与基材形成致密、无气孔的表面涂层。反之,则在涂层内出现许多空洞和气隙。 The wetting ability between the coating material and the substrate determines the quality of the laser coated structure, especially the laser coating of the preset coating. The wetting ability of the material after laser coating with the substrate to form a dense, non-porous surface coating. Conversely, there are many voids and gaps in the coating.
