超小型密封继电器推动杆部件烧结后的主要缺陷及探讨

摘要

超小型密封继电器推动杆部件烧结后的主要缺陷有歪头、平头和气泡，这些缺陷的存在降低了玻璃绝缘子的电性能和机械性能，如何控制和减少上述缺陷是推动杆部件烧结研究的重要课题。本文从玻坯密度、可伐合金的预氧化、玻璃绝缘子与烧结模的润湿等方面，对推动杆部件烧结后的主要缺陷进行了较详细的探讨。%After sintering , the main defects of the ultra -small sealed relay push rod parts incurred includes wryneck, flat head and bubble , the existence of these defects reduces the electrical and mechanical properties of glass insulator .How to control and reduce those defects is an important research topic of the push rod parts sinte -ring.In this paper , the defects on the push rod parts after sintering are discussed in detail from the density of glass, the pre-oxidation of Kovar , the wetting between glass insulator and sintering mould , etc.
