玻璃金属件的粘结已开发了多种方法,有(1)真空管等的气密采用玻璃熔敷法;(2)真空镀膜、金属喷镀、化学电镀、贵金属烧焊、Mo-Mn法等的金属喷镀法;(3)有机材料粘结等粘结方法,但这些方法对于玻璃板与金属件的粘结来说,有操作温度要求高,需要大型设备,而且粘结强度的耐久性差等缺点,很难工业化。直到现在,即使不考虑玻璃的强度,除连接点采取开孔加工外,还没有适当的方法。对于脆性材料的代表——玻璃一金属件的粘结,首先碰到的问题是由于两者热膨胀系数
Glass metal parts have been developed a variety of methods have been developed, there are (1) the vacuum tube and other airtight glass welding method; (2) vacuum coating, metal plating, chemical plating, precious metal welding, Mo-Mn method (3) Bonding method of organic materials, such as bonding, but these methods for the bonding of glass and metal parts, the operating temperature is high, requiring large equipment, and the poor durability of the bond strength Other shortcomings, it is difficult to industrialization. Until now, there has been no proper method except for drilling the connection points even without regard to the strength of the glass. For the representative of brittle materials - glass-metal bonding, the first problem encountered is due to the two thermal expansion coefficient
