The invention relates to a metal tile water lubricating friction pair structure. A whole circle embedded thrust face is adopted for a thrust disc, and the thrust disc is made from graphite or silicon carbide or ceramic or a carbon fiber reinforced composite. A thrust tile is a metal tile, and the thrust tile is made of double-phase high-chromium alloy or is obtained by carrying out hardened layer treatment on the surface of a common steel material. The surface hardness of the thrust tile is HRC45-65, and the surface hardness of the thrust disc is HS50-85. The thrust face of the thrust disc is convenient to demount and maintain, the thrust tile is provided with a full-metal heat-insulation-free nonmetal tile face, the tile face is free of harmful concave deformation in a thermal transient state, and high temperature, high pressure and irradiation are resisted. The friction pair structure can be widely applied to the fields of three-generation nuclear power plants, small floating heaps and ship and warship nuclear power.
