| 1. | Effect of rare earths on oxidation film thickness of 6063 aluminum alloy 微量稀土对6063铝合金阳极氧化膜厚度的影响 |
| 2. | Methods of evaluation for seal quality of positive polx oxidation film of alumimiun and alloy - admitance method 铝及铝合金阳极氧化膜封闭质量的评定方法导纳法 |
| 3. | With fine ability to clear off oxidation film , the width of clearing film can be adjusted continuously to make out good - looking welding seam 超强清理氧化膜能力,清理宽度连续可调,焊缝光亮美观。 |
| 4. | Then aligned carbon nanotube was grown on aao films . for one - step oxidation films , bamboo - shaped nanotubes were formed 然后在一次氧化和二次氧化的aao模板上沉积钴催化剂,用cvd法生长了纳米碳管。 |
| 5. | Through the analysis of the ablation phenomenon , some new techniques to improve the crafts to gain the wearable oxidation film and logical film ' s thickness and rigidity are put forward 为提高氧化膜的耐磨性,得到符合要求的氧化膜厚度和硬度,提出了新的工艺改进方案。 |
| 6. | The diamerter is even distributed and is much smaller than that of the holes . maybe there are several nanotubes grown from one hole . for two - step oxidation films , the diameter of the prepared nanotubes is the same as that of the holes 一次氧化的模板制备了直径均匀的竹节状碳纳米管,但直径径远远小于模板孔的直径,因此一个孔内可能长出数根碳管。 |
| 7. | The fracture strengh at room temperature of 95 . 2 % desity materials is lower than rbsc but higher than mosi2 ; the fracture toughness at room temperature is higher than mosi2 and reach the level of rbsc . when oxidated at 900 c , the evaporation of moo3 , co , co2 destroyed the oxidation film ( sio2 ) , the composite lost the weight because of the evaporation of moo3 . when oxidated at 1300 c , densitive oxidation film coverd the surface which composed by sio2 and mo5si3 在900氧化时,因为moo _ 3 、 co 、 co _ 2的挥发对氧化膜的破坏作用,无法在材料表面形成致密的sio _ 2氧化层,在该温度下复合材料表现为失重。在1300 ;氧化时,材料表面形成了致密的sio _ 2 、 mo _ 5si _ 3氧化层,复合材料先表现为失重,后表现为增重。 |
| 8. | Monthly production capacity of 300000 square feet of high - precision pcb board of double - layer and above , capable of production of circuit boards of various surface treatment process to customer ' s requirements , ranging from tin leveled board with lead to lead - free tin - leveled board , and from chemical nickel / gold plated board to even environ - friendly coated board with anti - oxidation film 月产能30万平方英尺双层以上高精密pcb板,可根据客户要求生产各种不同的表面处理的线路板,从有铅喷锡板至无铅喷锡板,从化学镍金板至更加环保的防氧化膜涂层板。 |
