项目摘要
Characteristics of adhesion between dissimilar metals under sliding friction were investigated to serve for cold pressure welding using interfacial slide. Pin-on-plate type sliding friction test was at first applied according to the research project. Aluminum showed strong adhesion, but a problem arose that iron, nickel and titanium chosen as the materials did not show adhesion at all. The problem and an additional difficulty that no information was presented on the effect of sliding length, one of important factors in actual joining processes, let us to stop using the friction test. Then a disc-on-disc type sliding adhesion test was employed in place of the pin-on-plate type test. In the sliding adhesion test, a pair of test- pieces joined each other at the interface by adhesion, and the strength of joining was measured as adhesive strength in order to estimate the degree of adhesiveness quantitatively from practical view point. Influences of the pressure and sliding length were examined, and after that adhesiveness in the various combinations including similar metal ones were evaluated. And the following suggestive information was obtained:1. Adhesive strength strongly depends on sliding length and shows a maximum at a certain sliding length. And the maximum shifts to shorter sliding length with an increase of the pressure. 2. An annealed material shows higher adhesive strength than work-hardened one in the same pressure. But taking flow stress into consideration, both are unified on behavior. 3. Adhesive strength shows a correlation with the threshold of reduction in height to start joining in cold pressure welding by upsetting. 4. Adhesive strength well expresses the degree of adhesiveness, and it can be used as the index to judge whether a particular metal combination is suited to apply cold joining process using interfacial slide.
研究了滑动摩擦条件下异种金属间的粘结特性,为界面滑动冷压焊接提供了依据。根据研究项目,首次采用销板式滑动摩擦试验。铝显示出很强的粘附性,但出现了一个问题,作为材料的铁、镍和钛根本没有粘附性。滑动长度是实际连接过程中的重要因素之一,这个问题和另外一个困难是没有提供关于滑动长度影响的信息,这让我们停止使用摩擦试验。然后用圆盘-圆盘滑动粘附性试验代替销盘-板式试验。在滑动粘接试验中,一对试件在界面处通过粘接相互连接,连接强度被测量为粘接强度,以便从实用的角度定量地评估粘接程度。考察了压力和滑动长度的影响,然后评估了包括相似金属组合在内的各种组合的粘附性。结果表明:1.粘接强度强烈依赖于滑移长度,在一定滑移长度时出现极大值。随着压力的增大,最大滑移长度向较短方向移动。2.在相同的压力下,退火后的材料比加工硬化的材料具有更高的粘结强度。但考虑到流动应力,两者在行为上是统一的。3.结合强度与冷压焊镦粗开始连接的高度降低门槛值呈正相关。4.结合强度很好地反映了结合的程度,可以作为判断某一种金属组合是否适合采用界面滑块进行冷连接的指标。
