The embodiment of the invention discloses a silicate passivation solution for multicomponent alloy co-permeation and a preparation method of a passivation permeation layer. The preparation method comprises the following steps: determining that the preparation process of the passivation permeation layer comprises the following steps: checking-gt before co-permeation; gt, alkali washing and oil removal; shot blasting activation-gt; preparing a permeating agent-gt; carrying out multi-component alloy co-permeation-gt; furnace charge separation-gt; cleaning and removing ash-gt; moisture drying-gt; silicate passivation-gt; performing centrifugal drying-gt; performing high-temperature curing; wherein in the silicate passivation process, the silicate passivation solution for multicomponent alloy co-permeation determined by the invention is adopted, and the silicate passivation process is executed by adopting process parameters obtained through an orthogonal test in advance, so that a passivation permeation layer is f
