WEAR-RESISTANT COATING

摘要

The invention relates to a wear-resistant coating, especially for gas turbine components, comprising a horizontally segmented or multilayered structure, i.e. at least one relatively hard, ceramic layer (24, 25, 26, 27; 36, 37, 38, 39) and at least one relatively soft, metallic layer (28, 29, 30, 31; 40, 41, 42, 43). The or each ceramic layer and the or each metallic layer are alternately arranged on top of each other in such a way that an external layer (27; 39) forming an external surface of the wear-resistant coating is embodied as a ceramic layer. According to the invention, at least the external, ceramic layer (27; 39) is segmented in a column-type manner in a vertical direction.
