Abstract
A soluble metal sealing ring with a controllable dissolution rate and preparation process thereof include an aluminum alloy sealing ring matrix and a composite coating coated on an outer surface of the aluminum alloy sealing ring matrix whose standard electrode potential is greater than −0.3 volts (V). The preparation process includes: (1) preparing a high-plastic aluminum alloy; (2) preparing the aluminum alloy sealing ring matrix by machining; (3) annealing the aluminum alloy sealing ring matrix; (4) mixing raw materials of the composite coating evenly; (5) preparing the composite coating on an outer surface of the aluminum alloy sealing ring matrix; (6) preparing holes. The soluble metal sealing ring solves problem that good sealing performance and good dissolving performance are difficult to obtain simultaneously in the existing product, and has advantages of good sealing performance, controllable dissolving rate, no blockage and others.
