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.
研究了滑动摩擦下异种金属之间的粘合特性,以用于利用界面滑动进行冷压焊接。根据该研究项目,首次应用了销板式滑动摩擦试验。铝显示出很强的粘合性,但是出现了选择作为材料的铁、镍和钛根本没有显示粘合性的问题。问题和另一个困难是没有提供有关滑动长度(实际连接过程中的重要因素之一)影响的信息,让我们停止使用摩擦测试。然后采用盘对盘型滑动附着力测试代替销对板型测试。在滑动粘合试验中,一对试验片通过粘合在界面处彼此接合,并且测量接合强度作为粘合强度,以便从实用角度定量地估计粘合程度。检查压力和滑动长度的影响,然后评估包括相似金属组合在内的各种组合的粘合性。得到以下提示性信息: 1.粘合强度很大程度上取决于滑动长度,并在一定的滑动长度处显示出最大值。随着压力的增加,最大滑动长度向更短的方向移动。 2. 在相同压力下,退火材料比加工硬化材料表现出更高的粘合强度。但考虑到流动压力,两者在行为上是一致的。 3. 粘合强度与镦粗冷压焊开始接合时的高度降低阈值相关。 4. 粘合强度很好地表达了粘合程度,可以作为判断特定金属组合是否适合采用界面滑动冷连接工艺的指标。
