Insulating ceramic ring of microwave magnetron
The invention provides a microwave magnetron insulating ceramic ring, which comprises an annular ceramic base body and metallization layers at the two ends of the annular ceramic base body, wherein the processing method of the metallization layer comprises the following steps: S1, preparing a plating assistant agent; S2, treating a high-purity aluminum block and a high-purity copper block; S3, pre-treating: soaking the annular ceramic base body in the hot plating assistant agent for 10-20 min, and then taking out for standby application; S4, carrying out single-sided hot dipping plating of aluminum and copper alloy; S5, carrying out double-sided hot dipping plating of aluminum and copper alloy; S6, cleaning the side wall; S7, electroplating a nickel layer; and S8, cleaning the side wall again. According to the invention, a reasonable matching technology of hot-dip aluminum-copper-plated alloy and ceramic crystalline phase particles is adopted to tightly combine the metallized aluminum-copper alloy layer with the ceramic body during sintering, and then the metallized nickel layer is electroplated on the metallized aluminum-copper alloy layer, so that the surface quality and the tensile strength of the ceramic metallized layer are greatly improved, and the service life of the magnetron is prolonged.
本发明提出了一种微波磁控管绝缘陶瓷环，包括环形陶瓷基体和环形陶瓷基体两端的金属化层；所述金属化层的加工方法包括以下步骤：S1.助镀剂的配置；S2.高纯铝块、高纯铜块的处理；S3.预处理：将环形陶瓷基体浸泡在热助镀剂中浸泡10‑20min后取出，备用；S4.单面热浸镀铝、铜合金；S5.双面热浸镀铝、铜合金；S6.侧壁清洗；S7.电镀镍层；S8.侧壁再次清洗。本发明采用热浸镀铝铜合金与陶瓷晶相颗粒合理匹配技术，使金属化铝铜合金层在烧结时能与陶瓷体形成紧密结合，然后再在金属化铝铜合金层上电镀一层金属化镍层，从而大大提高了陶瓷金属化层的表面质量和抗拉强度，延长了磁控管的使用寿命。
