EP - 3000 electrolytic polishing corrosion tester is a metallographic sample preparation instrument integrating electrolytic polishing and corrosion functions. It is suitable for use in factories, colleges and universities, scientific research institutions and other laboratories. This equipment makes use of electrochemical principle to prepare metallographic samples. It can also be used for polishing metallographic samples, and also for corrosion of metallographic samples. It has the advantages

According to GB/T4334 Corrosion of Metals and Alloys - Test Methods for Intergranular Corrosion of Stainless Steels, in order to check whether austenitic stainless steels have the tendency of intergranular corrosion, it is necessary to conduct U-shaped or S-shaped bending after the specified corrosion of the materials, and determine whether the materials have the tendency of intergranular corrosion by evaluating whether there are cracks in the bent parts.
This product is specially designed for U

PMTS-20 Portable Field Metallographic Inspection System

Clamp of metallographic cutting machine

LME-III macrostructure electrolytic etching device uses electrolytic etching method to prepare macrostructure samples according to GB226-2015 Steel Macrostructure and Defect Acid Etching Test Method.

1. Six side heating is adopted, and its temperature control and furnace temperature uniformity reach the international advanced level. The laboratory is used for heat treatment, especially for precision heating such as heating test of end quenching sample;

Intergranular Corrosion Instrument Sensitization Test-a Method Kit

Intergranular corrosion is a kind of local corrosion of metals, which usually occurs in stainless steel, aluminum alloy, brass and nickel base alloy. crystal
Intergranular corrosion is the corrosion extending inward along the boundary between metal grains. The reason of intergranular corrosion is the chemical formation between the surface and interior of grains
And the existence of grain boundary

1. The concentration of hydrochloric acid used in electrolytic acid etching method is only half of that of thermal acid etching method, and there is no need of heating, low temperature and less volatilization of hydrochloric acid, which significantly improves the working environment.
2. The device does not need to be preheated. Turn on the power supply to corrode and save time; Multiple rows of sa
