| 8. | The results showed that the effects of the experimental conditions and the preparation of specimens on contact angle were obvious . the additions of carbides to ti ( c , n ) solid solution could decrease contact angle of the system , the order was mo2c > tac > wc > vc > nbc , and the contact angle deceased continually with increasing the addition of other carbides or decreasing the ratio of tic in ceramics phase 研究发现实验工艺条件及试样制备都对接触角有一定影响;在ti ( c , n )固溶体中添加其它碳化物能够降低金属ni对ti ( c , n )固溶体的接触角,其对润湿性改善的强弱依次为mo _ 2c tac wc vc nbc ,并且增加碳化物添加量或降低tic的含量能使接触角持续下降。 |
| 9. | However the study of metal - oxide hetero - interface is relatively less because the properties of metals and oxides usually differ extremely from each other . contrary to metals , the oxides are usually very brittle , elastically stiffer , insulating and exhibit less thermal expansion and their crystal lattice constants are different from metals . moreover , the preparation of specimen of metal - oxide interface is very difficult , the observation of searching a suitable interface under the electron microscope is also a tedious work 然而,对金属-氧化物界面结构的研究却相对少一些,这主要是由于金属与氧化物之间的性质相差非常大,与金属相反,氧化物通常很脆、绝热、热膨胀系数小,晶格常数也不同于金属,有的甚至相差很大,而且,制备金属-氧化物界面比较困难,在电子显微镜下全面地观察一个合适的界面也是一项令人乏味的工作。 |
