易溶合金 的英文怎麼說
中文拼音 [yìrónggějīn]
易溶合金
英文
fusible alloy-
For electrodeposition by dc methods, the metals deposite uninterrupted and the particles were also embeded uninterrupted into the coatings ; for electrodeposition by pc method, the particles with biggish volume were desorbed from the coatings and returned to the electrolyte again owing to the presence of pulse interval ; for electrodeposition by prc method, the particles carried positive charges are much more easy to desorb from the coatings owing to the effecf of reverse pulse current combined with pulse interval, in addition, the reverse pulse current also could dissovle the metals, further accelerates the desorption of particles, thus the particles size embeded in the coatings by prc method is the least
直流電沉積時，基質金屬的沉積連續進行，粒子在電極表面不間斷嵌入鍍層;單脈沖電沉積由於脈沖間歇的存在使得具有較大體積的粒子會脫附，重新回到溶液中;採用周期換向脈沖時，反向脈沖電流使表面荷正電的較大的粒子更易從電極表面脫附，同時，反向脈沖電流對基質金屬的溶解作用，也會促進粒子的脫附，因此鍍層中復合粒子尺寸最小。隨著鍍層中粒子復合量的增加，三種鍍層的晶粒都明顯細化，說明al _ 2o _ 3的存在阻止了晶粒的長大，提高了電沉積過程中晶核的形成速率。Thermoplastic phenol - formaldehyde resin bond synthesized by solution po1ymeization is commonly used in making diamond grinding wheel, which has disadvantages such as : absorbing moisture, difficult mixing, can not being long term store, needing curing agent, and giving off dangerous gas
目前，金剛石樹脂砂輪普遍採用溶液聚合熱塑性酚醛樹脂作結合劑，此結合劑存在著易吸潮結團、混料困難、不易長期存放，需加固化劑才能固化，且固化過程中有大量的有害氣體溢出，使用時需要加工成粉末等缺點。It is notflammable without volatile organic solvent, benzene, heavy metal and irritant smell, being used safely and meeting the standard of construction
本品為非易燃品，不含揮發有機溶劑、苯、無重金屬、無刺激氣味、使用安全，符合施工標準。After adopting spinning nuzzle method, a lot of tic particles were got even at 720, and alti10 master alloy will be dissolved more easily
在改用旋轉噴頭加入c后，即使在720 ，也可以獲得較多的tic ，並且alti10中間合金也更容易溶解于al - si合金中。分享友人
