particle bonding 中文意思是什麼
particle bonding
解釋
顆粒粘結-
The melted tungsten carbide would react with the steel matrix on the interface and the reaction zone was observed as a result. the reacting production was examined as fe3w3c by means of x - ray diffraction and scanning electron microscopy analysis. the reaction between tungsten particle and steel matrix could improve the interfacial bonding strength remarkably
Wc鋼復合材料的制備過程中， wc顆粒在高溫下發生了局部溶解並在wc顆粒和鋼基體界面處發生了界面反應； x射線衍射和電子衍射花樣分析表明，反應產物為高穩定性的fe _ 3w _ 3c ，界面反應有效地改善了wc顆粒與鋼基體的界面結合。 -
It is found that, the sintering process of w - ni - fe - cu alloy was a typical liquid - phase process, which including particle rearrangement stage, dissolving - precipitation stage and solid - phase sintering stage. cu plays an important role in the particle rearrangement stage, while fe can promote the densification by forming ni - fe - w bonding - phase. ni can not only form the bonding - phase, but also enhance the diffusion between the w grains
研究表明， w - ni - fe - cu合金的液相燒結緻密化經歷了顆粒重排、溶解-析出和固相燒結等三個階段， cu僅在顆粒重排階段起主導作用； fe主要在溶解-析出階段通過形成ni - fe - w三元粘結相來促進w合金的燒結緻密； ni不僅參與形成ni - fe - w三元粘結相，並且在w晶界上通過與w的互擴散促進了固相w晶粒的粘合。
