The invention discloses a thermometal thrust bearing bronze sheet and steel base forming process. The thermometal thrust bearing bronze sheet and steel base forming process sequentially includes preparing bearing blank of a steel base; setting a pouring groove of a center shaft of the bearing blank on a combined surface of the bearing blank and the bronze sheet, cleaning, hot tinning and drying; cutting ring slots of distance from 3-4 mm and profile peak height from 0.8 mm to 1.2 mm in the bottom surface of the pouring groove, and filling fusible borax in the thickness of 5-25 mm into the pouring groove; disposing the bearing blank in a heating furnace at the temperature 950-970 DEG C, heating the temperature to 950-1050 DEG C for 10-35 min, taking the bearing blank out in the fused borax environment and pouring bronze within 24 hours after hot tinning to form the bronze sheet of the thrust bearing. The steel base and the bronze sheet have firmer combination force and the thermometal thrust bearing bronze sheet and steel base forming process is reasonable, simple, feasible and convenient to operate; layering within test and use time of products is avoided, adhesion strength of separation and displacement between the bronze sheet and the steel base is 275 MPa and 182 MPa respectively by measuring.
