銅絲活化 的英文怎麼說
中文拼音 [tóngsīhuóhuà]
銅絲活化
英文
copper wire activation-
A reliability experiment of thermal aging was carried out for the two types of joints, scanning electron microscopy, energy dispersive x - ray spectrometer and micro x - ray diffractomer were adopted to investigate the interfacial evolution behavior of joints, and kinetics model of imc formation was established. the results show that imc growth follows the parabolic law as a function of aging time at certain aging temperature, imc growth is more sensitive to the aging temperature than the aging time, the activation energy of cu - al imc growth is 97. 1kj / mol and the major forming cu - al imc are cual2 and cu9al4, the activation energy of au - al imc growth is 40. 1kj / mol and the main au - al imc are au4al and au5al2, with au2al and aual at the interfacial periphery of joints, the rate of cu - al imc growth is about 1000 times slower than that of au - al imc, and kirkendall voids and cracks are easily appeared during thermal aging in gold ball bonds while voids and cracks are absent in copper ball bonds even after aging at 200 for 2900 hours and 250 for 169 hours
研究結果表明:金屬間化合物厚度與老化時間的關系符合拋物線法則，金屬間化合物的生長對老化溫度比老化時間更加敏感; cu - al金屬間化合物生長的激活能為97 . 1kj / mol ，老化后金屬間化合物呈層狀分佈，主要相為cual2和cu9al4 ; au - al金屬間化合物生長的激活能為40 . 1kj / mol ，主要相為au4al和au5al2 ，同時在界面周邊區域生成了au2al和aual ;老化過程中cu - al金屬間化合物生長速率比au - al金屬間化合物生長速率小103數量級;金絲球鍵合點200老化96小時出現了明顯的kirkendall空洞和裂紋，但銅絲球鍵合點200老化2900小時和250老化169小時都沒有形成空洞和裂紋。Jian can ' t be saved - - the iron is loose completely, the case rises and is broken, the scabbard calcifies and become a suit with the blade. there ' re a lot of silk, broken wood. due to the wooden scabbard, the cautery material can ' t be dunked out. this scabbard still has a little color, which is paint, red. i estimate it will disappear soon
劍已沒救- -鐵質已徹底蓬鬆，從劍心裏頭漲出來，象千層糕，把格（銅制）都漲破了，木鞘也已鈣化得和刃成為一體（有點象樹木的化石） .絲綢，殘木等付著物也較多.由於劍付著木鞘，拔不出來，也就沒法泡出劍里活躍性腐蝕物質了（恐怕也不必了） .這鞘還存有一點彩，是漆，紅的.估計很快也會消失了
