Zusammenfassung:	The invention discloses a preparation method of GH4169 powder with high phosphorus and boron elements for SLM (selective laser melting), which is specifically implemented according to the following steps: step 1, preparing nickel chloride, glycolic acid, sodium hypophosphite and diimino borane as raw materials into a chemical plating solution according to a molar ratio of 1: (3-6): (3-6): (3-6); 2, GH4169 alloy powder prepared through a plasma rotating electrode method and screened is added into the chemical plating solution prepared in the step 1, then the GH4169 alloy powder is heated and stirred to be uniform, and finally the GH4169 alloy powder is deposited; and (3) the GH4169 alloy powder obtained in the step (2) is dried, and the GH4169 powder with high phosphorus and boron elements is obtained. According to the preparation method of the GH4169 powder with the high phosphorus and boron elements for the SLM, the problem that phosphorus and boron are difficult to add into the GH4169 powder by using an exi
