316L stainless steel fiber felt was used as raw material. Sound absorption properties of the porous materials before/after corrosion were measured through the double pipe microphone impedance method. The law of the sound absorption properties was discussed also. In addition, the microstructure of the porous materials was observed by SEM. Some results are concluded as follows: when the hydrochloric acid (HCL) concentration is 1wt%, the sound absorption coefficient of the porous materials before/after corrosion is invariable generally. When the HCL concentration is 10wt%, the one after corrosion is higher than before corrosion, about 0.2 (4000~6000Hz), due to the corrosion pits at the face of the fibers.

Surface Morphologies

A novel sintered stainless steel fiber felt (SSSFF) with rough surface morphologies and high strength as well as high porosity is fabricated by solid-state sintering of stainless steel fibers produced by cutting method. The rough surface morphologies are characterized by laminar and jagged structures formed on the surface of stainless steel fibers. The SSSFF with 85% porosity sintered at 1200°C for 60 min exhibits tensile strength of 19 MPa and yield stress of 10.5 MPa. The influence of sintering parameters on surface morphologies and tensile strength is investigated. The experimental results show that the rough surface structures will disappear gradually when sintering temperature is 1300°C or sintering time is excessive, that is, 240 min when sintering temperature is 1200°C. The SSSFF with high porosity presents high tensile strength when sintering temperature ranges from 1100°C to 1200°C and sintering time is from 60 min to 120 min. In addition, the fracture mechanism of the SSSFF is investigated when subjected to uniaxial tensile load.
