Protective layer (environmental barrier layer) for titanium aluminum materials against environmental impact

The invention relates to a surface coating for protecting a substrate containing a titanium-aluminum material, preferably containing one or more of the materials from Table 1, the coating comprising a sequence of layers having at least one layer which forms a diffusion barrier for titanium, preferably corresponding to one or more of the sequences given in the rows of Table 1, and the coating comprising at least one of the layers, preferably corresponding to one or more of the sequences given in the rows of Table 1. The coating comprises an oxidation barrier, which is matched in particular to the diffusion barrier, preferably in accordance with Table 2, and in particular wherein the surface coating comprises a thermal barrier, which is matched preferably in accordance with Table 3, to the oxidation barrier. 本发明涉及一种用于保护含有钛铝材料的基材的表面涂层，其优选含有来自表1的材料中的一种或多种，其中，该涂层包含具有至少一个层的层序，该层针对钛形成扩散阻挡，最好对应于在表1的行中给出的层序中的一个或多个，并且其中，该涂层包括尤其与扩散阻挡匹配、最好按照表2匹配的氧化阻挡，并且尤其是其中，该表面涂层包括最好按照表3匹配于氧化阻挡的热阻挡。
