In this thesis, the phase diagram of Zn-Al binary system on 10~69.5 w% was reinvestigated by using differential scanning calorimeter, X-ray diffraction and pushrod dilatometer. The process of isothermal transformation during the aging of high-Aluminum-Zinc-based alloy was studied by using differential scanning calorimetry, and the aging behavior of the alloy was analyzed at the aspect of thermal analysis kinetics. The change of microstructure which the alloy was being heated was observed on high-temperature metallurgical microscope. The microstructure and wear-friction properties were compared among the alloys treated with several different heat treatment processes, and a model for heat treatment processes was proposed based on artificial neural network,so as to predict the relationship between friction coefficient and parameters of aging treatment such as aging temperature and time.

And then to study the both structures' emission characteristic.It was found that the Al-AlN could emit electrons. The two different structures' emission efficiency has prodigious distinction. The first one whose electron emitter film is on the top was much easier to engender the straitens gaps. And it could engender the straitens gaps at larger area than the other one.

经过实验我们发现(1)对于发射层位于电极之上的结构观测到可测量的发射电流(2)当电子发射层位于电极之上，一排电子发射单元的总电阻介于20~150Ω之间时，电形成过程中，给电极间加脉冲电压，在第一个脉冲周期中就能把Al-AlN电子发射薄膜烧断；而对于电子发射层位于电极之下的结构，在电形成过程中，则需要几个脉冲周期之后才能将电子发射薄膜烧断。
