MODEL DPF-2 ELECTROLYTIC POLISHING AND ETCHING INSTRUMENT
DPF-2 electrolytic polishing &
etching
instrument is
a metallographic sample making instrument that integrates electrolytic polishing
and
etching functions,
suitable for use in laboratories
of factories,
colleges, and research institutions. The instrument adopts the principle of
electrochemistry to prepare metallographic samples. The metallographic samples
prepared by electrolytic polishing and
etching avoid
the deformation layer caused by mechanical polishing, so their structure is real
and without artifacts. It is an excellent method for preparing non-ferrous
metals and high-temperature alloy samples such as titanium, aluminum, copper.
This instrument is designed with high working voltage and high working current,
leaving a large margin for the metallographic preparation of large-sized
specimens. It is particularly suitable for the preparation of welded
metallographic specimens and is a classic choice for polishing final
metallographic specimens.
Features
-
Touch screen operation, the interface is
intuitive and easy for operation.
-
The maximum output of voltage is
60V DC, and current is 25A, which can meet the high voltage
and high current requirements for electrolytic polishing of special
materials and large-area samples.
-
It has stable low
voltage output, meeting the requirements for preparing special sample
metallographic structures.
-
It can accurately and continuously adjust the
working voltage or current, operate the knob, and display real-time on the
touch screen.
-
The electrolysis time of the sample can be set
and the electrolysis can be timed to end.
-
Equipped with an electrolyte circulation device,
the flow rate is controllable, and fresh corrosion solution can continuously
corrode the material during the sample preparation process, taking away the
corrosion products on the sample. The polishing effect is better than other
stirring methods.
-
The distance between the cathode and anode of
the equipment is fixed, which can ensure consistent corrosion parameters for
each sample.
-
Prepare the sample at the required current
density through a certain diameter orifice plate and a set electrolysis
current.
-
The equipment is equipped with a corrosion
liquid temperature display and a corrosion liquid cooling device, which can
cool the corrosion liquid in operation through cooling water or other
cooling media.
-
The electrolyte container is made of
corrosion-resistant materials and has a corrosion liquid recovery device,
which facilitates the recovery of corrosion liquid.
-
The instrument host is equipped with external
output contacts on the back, making it convenient for samples with special
needs to be prepared by electrolysis using other containers or methods.
