The invention relates to a mechanical seal assembly comprising a mechanical seal with a rotating slide ring (3) and a stationary slide ring (2), wherein one of the two slide rings has a first slide surface (30), wherein the other of the two slide rings has a second slide surface (20) with a circumferentially closed sealing blade (22) which protrudes from a bottom region (21) of the second slide surface in the direction of the first slide surface (30) by a height (H), wherein the sealing blade (22) has a width (B) in a range of between 10 and 500 μm, wherein at least one pre-tensioning element (4) braces the slide rings against each other, wherein the second slide surface (20) and the sealing blade (22) on the second slide surface (20) have a diamond coating, or wherein the second slide surface (20) and the sealing blade (22) on the second slide surface (20) have a coating of cubic boron nitride, and wherein an OH−-ion donor (10) and or an H+ ion donor (10) is present between the first slide surface (30) and the second slide surface (20).
