WebSep 1, 2012 · 2-μm-thick CrN–Ag composite coatings containing 22 at.%Ag were deposited on Si(001) by reactive co-sputtering at T s = 300, 400, and 500 °C. Subsequent vacuum annealing at T a = 425, 525, and 625 °C causes Ag transport to the surface. Auger electron spectroscopy and plan-view microscopy are used to quantify the Ag transport to the … Web(3)随钎焊时间和钎焊温度的增加,钎焊界面上Cu6Sn5晶粒个数逐渐减少,大晶粒长大,小晶粒减小至最后消失的现象可以用Gibbs-Thomson效应来解释。 晶粒半径越小,所含的Cu浓度越大,造成Cu元素向相邻的大尺寸晶粒中的扩散。

The technique is closely related to using gas adsorption to measure pore sizes, but uses the Gibbs–Thomson equation rather than the Kelvin equation. They are both particular cases of the Gibbs Equations of Josiah Willard Gibbs: the Kelvin equation is the constant temperature case, and the Gibbs–Thomson … See more The Gibbs–Thomson effect, in common physics usage, refers to variations in vapor pressure or chemical potential across a curved surface or interface. The existence of a positive interfacial energy will increase the energy required … See more The Gibbs–Thomson equation may be written in a compact form: where the Gibbs–Thomson coefficient In more detail:, See more For an isolated spherical solid particle of diameter $${\displaystyle x}$$ in its own liquid, the Gibbs–Thomson equation for the structural … See more Very similar equations may be applied to the growth and melting of crystals in the confined geometry of porous systems.
