Various degradation mechanisms, however, may appear such as chemical instability between different components of cells and sintering of electrode materials especially during a long-range operation at high temperatures.
On the cathode side, most of earlier studies on degradation were conducted on chromium poisoning effect, which is mainly caused by metallic interconnect materials and leads to serious degradation of cells [6, 7].

Titanium alloys are labeled as difficult to materials because of their low machinability rating.
These alloys are termed as “Difficult-to-cut materials” because of their low machiability rating.
Wear mechanisms such as adhesion, abrasion and diffusion depends on the tool and workpiece materials and the cutting temperature.

Introduction Vibration and impact are the most common external excitation in packaging system, the amount of energy absorbed by the packaging materials, when the packaged product reach its ultimate bearing strength , is an important index in packaging evaluation, the bigger the better.
Suppose the mass of an electronic product is m = 6 kg, and the contact area between the packaging materials and it is 0.05 m2.
