Beschreibung
Zusammenfassung:	The invention discloses a method for treating the surface of a high-strength fastener, relates to the field of methods for treating the surfaces of fasteners in the field of fasteners, and aims to solve the problem that a fastener is cracked or damaged due to the fact that hydrogen embrittlement is easily generated in the treatment process of an existing treatment method. The method comprises thefollowing steps: step 1. degreasing; step 2. removing oxide skin by laser; step 3. performing electroplating treatment; step 4. performing hydrogen embrittlement reduction processing; step 5. performing chromate passivation treatment; step 6. performing drying treatment; step 7. coating grease; and step 8. taking out and draining. 本发明公开了一种高强度紧固件表面的处理方法，涉及紧固件领域中紧固件表面的处理方法领域，为解决现有的处理方法在处理的过程中易产生氢脆，从而使紧固件出现开裂或损伤的现象。包括如下步骤：步骤一：去油污；步骤二：激光去除氧化皮；步骤三：电镀处理；步骤四：降低氢脆加工；步骤五：铬酸盐钝化处理；步骤六：干燥处理；步骤七：涂覆油脂；步骤八：取出沥干。
