Test Background
Sintered metal porous materials are 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 fatigue performance test of sintered metal porous materials can determine the fatigue properties of sintered metal porous materials. Zhongke Testing Reliability Experiment Center has the capability of reliability testing of various sintered metal porous materials, and provides professional fatigue performance testing services for sintered metal porous materials.
Scope of tests
is suitable for sintered metal porous materials produced by powder metallurgy method, and is not suitable for dense metal materials.
Test method
1. Clamp the sintered metal porous material sample on the fatigue testing machine, apply axial cyclic stress to the sample, and continue until failure or until a preset stress cycle is exceeded.
2. Test the relationship between applied stress and failure cycles of sintered metal porous materials under different stress ratios.
