DPF-1 type electrolytic polishing corrosion testerDetailed product description：

Purpose:
The DPF-1 electrolytic polishing corrosion tester is a metallographic sampling instrument that integrates electrolytic polishing and corrosion functions. Suitable for use in laboratories such as factories, colleges, and research institutions.

Features:
The instrument uses electrochemical principles to prepare metallographic samples. The metallographic samples prepared by electrolytic polishing and corrosion avoid the deformation layer caused by mechanical polishing, so their structure is real and without illusions. Therefore, it is the best method for preparing samples of non-ferrous metals such as titanium, aluminum, copper, and high-temperature alloys. This instrument is designed with high working voltage and high working current, leaving a large margin for metallographic preparation of large-sized specimens, especially suitable for the preparation of welded metallographic specimens.
The instrument has the characteristics of continuous, stable and adjustable current and voltage output for electrolytic polishing and corrosion, and real-time display of working voltage, current, polishing (corrosion) time and electrolyte temperature, which can easily reproduce polishing and corrosion processes. This is extremely advantageous for evaluating the metallographic structure and hot processing technology of materials; The instrument has the characteristics of adjustable working distance and polishing (corrosion) area, which can be flexibly adjusted according to the actual situation of the sample. Therefore, it is suitable for the preparation of metallographic samples of various materials, shapes, and sizes.
The instrument uses a special method to circulate and cool the electrolyte, resulting in high polishing efficiency and better polishing effect than other stirring methods.
The instrument circuit adopts a traditional combination of transformers and switching power supplies, which not only ensures stable and continuously adjustable working voltage (current) output, but also completely isolates the output terminals of the electrolytic polishing and corrosion power supplies from the high-voltage input power supply, ensuring the safe use of the operator. The instrument casing is made of stainless and acid resistant steel structure, and the storage tank is made of special acid resistant materials to ensure long-term reliable use of the instrument.
