| http://www.w3.org/ns/prov#value | - It has been found that if the thickness of the intermediate layer is 15-60 ??m, in particular 35-50 ??m and more particularly 35-<50 ??m, the fatigue strength is somewhat higher than for greater thicknesses of the intermediate layer, where values for the fatigue strength higher than 100 MPa can be achieved.
