ABSTRACTA cooling device for use with the Fishione twin-jet electropolisher Model 110 has been developed for electropolishing TEM specimens at controlled and low temperatures necessary for some materials. This consists of an explosion-proof pump circulating methanol through a specially designed stainless steel bath, and a copper coil immersed in a mixture of methanol and dry ice in a dewar. A thermocouple with a temperature control unit provides precise temperature control.With this device, electropolishing can be conducted at temperatures as low as −55°C. This allows electropolishing of certain materials which cannot be polished with conventional equipment. The precisely controlled temperature also improves the performance of the electropolishing equipment at all temperatures because the success of electropolishing depends on maintaining constant conditions during the process. The unit further allows the use of aggressive electrolytes and preparation of solutions which could otherwise become hazardous due to heat buildup during electropolishing or preparation.

In this paper,we analysed the problems that existed in the extrusion hot embossing process.To slove these problems,we designed a new extrusion hot embossing process and verified the effectiveness and feasibility of this process through experiments.The thickness and temperature of the extruded polymer film were affected by various factors.It is very difficult to ensure the uniformity of thickness and temperature before the polymer film enters into the hot embossing machine.Therefore,we add a planish unit and a temperature control unit to ensure the uniformity of thickness and temperature of the polymer film.At the same time,we produce the polymer film with microstructure on its surface by this two differern process sepatately and make some tests.The results show that:the new process greatly improved the uniformity of the thickness and temperature compared with the original embossing process.In this new process the uniformity of the thickness and temperature was better ensured.
