An erosion and CMAS resistant coating arranged on a TBC coated substrate and including at least one porous vertically cracked (PVC) coating layer providing lower thermal conductivity and being disposed over a layer of MCrAlY wherein M represents Ni, Co or their combinations. At least one dense vertically cracked (DVC) erosion and CMAS resistant coating layer is deposited over the at least one PVCcoating layer. 一种耐侵蚀和耐CMAS涂层，其布置在TBC涂布的基底上并包括至少一个提供较低热导率并布置在MCrAlY层上的多孔垂直裂纹（PVC）涂层，其中M代表Ni、Co或它们的组合。在所述至少一个PVC涂层上沉积至少一个致密垂直裂纹（DVC）耐侵蚀和耐CMAS涂层。
