Sealing ring member for turbine comprising angled cavity made of an abradable material

The invention relates to a sealing element for a turbine. The sealing element is used for providing sealing between two elements of the turbine, and the sealing element comprises a sealing ring element (6s) and a wiper (2L). The sealing ring element comprises a sealing part (6p) having a first region (6p1) and a second region (6p2), the inner surface (6i) of the first region (6p1) is the same radial distance as the axis of the turbine (x), and the sealing part (6p) comprises an annular cavity (6c) which leads to the inner surface of the second region (6p2), and the annular cavity (6c) extendsinto the first region (6p1), and the annular cavity (6c) defines an upstream side wall (6m) and/or a downstream side wall (6v), the upstream side wall (6m) and/or the inner surface (6i) of the downstream side wall and the first region (6p1) forms an angle (alpha) strictly between 0 and 90 degrees, such that a portion (P) of the wear-resistant material of the first region (6p1) is superimposed radially in the annular cavit
