前几年,硬质合金刀片供应比较紧张,我们曾试用陶瓷刀片。那时采用装夹法,将陶瓷刀片装在刀杆上,但刀片经常被夹碎,刃磨也磨不好。后来,我们一面试用,一面寻找较为合适的焊接法,曾用铜、铁、水泥、树脂、明矾、有机胶等来粘结,也曾用氟化钠作焊结剂来焊接,但都不理想。以后,我们把刀片与刀杆分开来摸索研究,由于刀杆是金属制的,刀片是瓷制的,就从金属方面寻找与瓷的粘结剂,从瓷的方面寻找与金属粘结的东西,最初亦没有找到能解决问题的线索。有一天,我在喝开水,发现一只搪瓷杯上打掉一块瓷,在掉瓷的地方生了锈,使我联想到杯子的里层是铁,外层是瓷,这就明瓷与铁可以粘在一起。
A few years ago, the supply of hard alloy blades more nervous, we have tried ceramic blades. At that time using clamping method, the ceramic blade mounted on the arbor, but the blade is often broken, sharpening grinding is not good. Later, when we tried to find a more suitable welding method, we used copper, iron, cement, resin, alum, organic glue and so on, but also used sodium fluoride as a soldering agent to weld, but neither was ideal . Later, we separated the blade and arbor to explore the research, because the arbor is made of metal, the blade is porcelain, from the metal to find the bonding agent with the porcelain, from the ceramic aspects of looking for bonding with metal , Did not find the clues to solve the problem at first. One day I was drinking boiled water and I found a porcelain cup knocked down a piece of porcelain, porcelain rusty place reminds me of the inner layer of the cup is iron, the outer layer is porcelain, which is porcelain and iron Can be glued together.
