pecht 中文意思是什麼

pecht 解釋
佩希特
  1. Thus atom diffusion is a ' key factor to pecht. how do atoms diffuse under bpec heating

    因此，原子的擴散是決定脈沖大電流熱加工的重要因素。
  2. And is it the same as under radiation heating ? do the special electric and magnetic fields produced by bpec accelerate atom diffusion ? understanding the above questions fully is a key to expose the mechanism of pecht

    在脈沖大電流加工過程中原子是如何擴散的，與一般的加熱燒結、焊接是否一樣，脈沖大電流形成的特殊電場及磁場是否對原子的擴散有大的推動作用，弄清這些問題成為進一步揭示脈沖大電流熱加工機理的關鍵。
  3. Pulse electric current heat treatment ( pecht ) developed by sodick, ltd., of japan, is a recently developed material processing method which consists of spark plasma sintering and welding, plasma activated sintering and welding, big pulse electric current ( bpec ) diffusion welding etc. the following are basic merits of pecht : rapid heating and cooling ; short sintering or welding time ; lowering sintering or welding temperature

    脈沖電流熱加工（ pulseelectriccurrentheattreatment ，比如燒結，焊接等）是九十年代發展起來的一種材料快速制備新技術，它包括放電等離子燒結與焊接、等離子活化燒結與焊接、脈沖大電流擴散焊接等。它具有升溫、降溫速度快、能在較低的溫度下燒結或焊接以及時間短的特點。
  4. As a matter of fact, pecht is achieved by atom diffusing

    實際上，脈沖大電流熱加工過程是由原子的擴散過程來實現的。
  5. Why pecht is so quick is a hot topic and many scholars are trying to explain it by proving plasma generating

    脈沖大電流燒結、焊接為什麼如此之快是各國研究人員探索的熱點，多數學者從證明形成等離子的角度來解釋這一現象。
  6. While sintered by radiation heating, the average pore size decreased slowly with increase of temperature at first, and then fell sharply, showing that the pecht technique could achieve consolidated structure at relative low temperature. fe was sintered at on / off of 6 / 1, 12 / 2, 24 / 4, 48 / 8

    脈沖大電流燒結fe顆粒材料，燒結體孔徑平均值隨溫度呈波浪關系;輻射加熱燒結體的孔徑平均值隨溫度的升高先緩慢減小，繼續升高溫度，孔徑平均值急劇減小。
