Beschreibung
Zusammenfassung:	The invention discloses a nuclear power equipment bolt phosphating method which comprises the following step: S1, pretreating equipment bolts: firstly soaking the bolts in an oil removing solution toperform oil removing treatment, washing under the normal temperature after oil removing, utilizing hydrochloric acid to perform acid pickling after washing, washing again after acid pickling and thenperforming surface conditioning; S2, soaking the pretreated bolts in a phosphating solution for a first preset duration to perform pre-phosphating; S3, retreating the pre-phosphated bolts: washing thebolts again, utilizing hydrochloric acid to perform acid pickling after washing, washing again after acid pickling and then performing surface conditioning; S4, soaking the retreated bolts in the phosphating solution again for a second preset duration to perform phosphating. The invention further provides the phosphating solution. By means of the nuclear power equipment bolt phosphating method and the phosphating solution
