Özet

In the present paper, effects of pitting corrosion on the strength of members made of AISI 410 Martensitic stainless steel were investigated. Stainless steel compressor bladesin power generation industries commonly suffer from pitting corrosion.Pits geometry analysis and strength tests have been conducted.Pits geometry analysis established the maximum pit depth of 0.26mm along with the maximum diameter of 1mm. In addition, strength and elongation of the pitted tensile specimen gradually decrease with the increase of the area lost due to pitting corrosion.A damage nucleation phenomenon at the initial load values is also postulated. © (2014) Trans Tech Publications, Switzerland.
