Sulfurization corrosion test of sintered metal porous materials

sintered metal porous material is a functional material that is developing rapidly at present. It has the advantages of good permeability, adjustable pore size, corrosion resistance, high temperature resistance, and high strength. It can be made into filters, separation membranes, silencers, catalyst carriers, battery electrodes, flame retardant and explosion-proof materials, and has been widely used in atomic energy, petrochemical, metallurgy, machinery, medicine, environmental protection and other industries.
The sulfide corrosion test of sintered metal porous materials can determine the sulfide corrosion properties of sintered metal porous materials. Zhongke Testing Reliability Experiment Center has the reliability testing capabilities for various sintered metal porous materials, and provides professional sulfide corrosion testing services for sintered metal porous materials.

is suitable for sintered metal porous materials produced by powder metallurgy methods, including sintered metal powder porous materials, sintered metal fiber porous materials and metal foam materials.

1. By simulating the sulfide working conditions, the sample is placed in a hydrogen sulfide gas or sulfate corrosion environment, kept at the test temperature for a certain period of time, and the sulfide corrosion performance of the sintered metal porous sample is tested by comparing the weight change of the sample before and after corrosion.
2. If necessary, the sulfidation corrosion performance of sintered metal porous materials can also be characterized by testing the pore properties of the sample before and after corrosion, such as the maximum pore diameter and the change rate of air permeability.
