在铸铁面上粘牢一层巴氏合金,对动力工业或机械工业都很有用,但铸铁含有的炭,矽,錳磷硫等杂质较钢为多,特别是游离炭,它阻碍巴氏合金与铸铁的粘牢,这里的研究是用酸性溶液来在铸铁面上进行产生较纯的铁层,然后用鹹性溶液沸煮,并用软铜丝刷重刷铸铁需加合金之一面,通过鹽酸溶液,及热的氯化鋅溶液,然后进行镀焊剂及浇入巴氏合金,在鍍焊剂时,必需严格控制温度与时间,而在浇入巴氏合金时必需控制铸模温度和浇铸温度,合金铸入后冷却情况亦需适宜。用这样的方法来把巴氏合金浇铸在铸铁面上,其粘牢程度很好,经过很多次的试验机试验,得到铸铁与巴氏合金间的粘牢力是320公斤/厘米~2,这是为适合一股工业上应用而在靜模浇铸所得的结果。如专为制原动力机的軸承的话,可用离心浇铸,这样,铸铁与巴氏合金间的粘牢力还可较上面所得数字高一些。
Sticky on the cast iron surface, a layer of Babbitt alloy, the power industry or mechanical industry are useful, but the cast iron contains carbon, silicon, manganese and phosphorus and other impurities than steel, especially free carbon, which hinder the Babbitt And cast iron sticky, the research here is to use acidic solution to produce pure iron layer on the cast iron surface, and then boiled with salt solution, and with a soft copper wire brush brush to brush the need to add one side of the alloy, through the hydrochloric acid solution , And hot zinc chloride solution, and then carry out fluxing and pouring pasteurized alloy, the flux must be strictly controlled when the temperature and time, and when poured into the Babbitt must control the mold temperature and casting temperature, alloy cast Into the cooling conditions also need appropriate. In this way to Babu alloy cast on the cast iron surface, the adhesion is very good, after many tests on the test machine, the bond between the cast iron and Babbitt was 320 kg / cm ~ 2, which It is the result of static casting for a commercial application. If the original system for the power generator bearings, then centrifugal casting, so that the adhesion between cast iron and Babbitt alloy can be higher than the figures obtained above.
