Overview
DPF-2 electrolysis polishing and corrosion instrument is a metallographic sample preparation instrument of YUZHOU brand that integrates electrolysis polishing and corrosion functions. It is suitable for laboratories such as factories, Universities & colleges, scientific research institutions, etc. The instrument adopts electrochemistry principle for metallographic sample preparation, avoids the deformation layer caused by mechanical polishing, and ensures that the structure is real and free of artifacts. It is especially suitable for the preparation of non-ferrous metals and superalloy samples such as titanium, aluminum, and copper. It has a high Operating voltage and a large Operating Current, leaving margin for larger size samples. It is a classic choice for welding metallographic sample preparation and final polishing.
Features
1. The maximum output of the power supply part is 60 volts DC voltage and 25 abe current, which meets the high voltage and high current requirements of special materials and large-area sample electrolysis polishing.
2. With stable low voltage output, it meets the preparation requirements of metallographic structure of special samples.
3. Operating voltage or current can be adjusted accurately and continuously, knob operation, Touchscreen real-time display.
4. The sample electrolysis time can be set, and the electrolysis can be ended regularly.
5. With electrolysis liquid circulation device, Flow velocity is controllable, during the sample preparation process, fresh corrosion liquid is constantly corroding the material and taking away corrosion products, and the polishing effect is better than Miscellaneous Mixing method.
6. The distance between the cathode and the anode of the equipment is fixed to ensure that the corrosion parameters of each sample are consistent.
7. Through a certain diameter orifice plate and setting the electrolysis current, the sample is prepared at the required Current density.
8. The equipment has corrosion liquid temperature display and chill down device, which can chill down the corrosion liquid during work by chilling down water or Miscellaneous chill down medium.
9. The electrolysis liquid container is made of corrosion-resistant materials and has a corrosion liquid recovery device, which is convenient for corrosion liquid recovery.
10. The back of the instrument host is equipped with an external output contact, which is convenient for samples with special needs to use Miscellaneous containers or methods for electrolysis preparation.
Principle
The instrument uses the principle of electrochemistry to prepare metallographic samples, and avoids the deformation layer caused by mechanical polishing through electrolysis polishing and corrosion process to ensure that the tissue is real and free of artifacts.
Applications
Universities & colleges, laboratories, etc
