Shot Peening or Ceramic Thermal Spraying for Controlling the Delayed Fracture

Mikio Takemoto, Motoaki Nakamura, Shuichi Ueno

pp. 192-207

DOI:

10.3323/jcorr.71.192

Abstract

Authors studied how we could control the delayed fracture of three point bent spring steel using shot peening or thermal spraying of oxide ceramic. We first introduce properties of the shot peened spring steel and then explore the effect of hydrogen-supplement method （hydrogen charge） on the susceptibility of delayed fracture. Next we discuss threshold strains by Conventional Immersion Test （called as CIT method） of bent specimens. Further, we propose an alternate evaluation method using acoustic emission （AE）. Here we determine the threshold strain by measuring AEs during Step-wise Strain Increasing （SSI-AE method） of hydrogen pre-charged specimens. We introduce two cases where the shot peening can or can’t control the delayed fracture, depending on both the hydrogen charge method and the strength level of the steel. We also discuss problems and advantages of the CIT and SSI-AE methods. We studied a method for controlling the diffusion rate of hydrogen into the steel using thermal spraying of conductive titania, and demonstrated how this method was effective for improving the threshold strain for the system where the shot peening could not be an effective countermeasure against the delayed fracture.

Effects of Metal Cations on Corrosion Morphology of Carbon Steel in Model Fresh Water

Li Li, Masatoshi Sakairi

pp. 208-212

DOI:

10.3323/jcorr.71.208

Abstract

The effects of metal cations on corrosion morphology of carbon steel immersed in model fresh water were investigated by surface observation and analysis. Different surface and cross-sectional morphologies were observed by scanning electron microscope. The X-ray photoelectron spectroscopy and cross-sectional Auge electron spectroscopy point analysis results suggested that the corrosion products formed in Zn2＋ containing solution contained Zn compounds.

Evaluation of Fracture Strength of Corroded Steel Bolted Joints Using Acoustic Emission Method

Takuma Matsuo, Koya Tokuhara

pp. 213-217

DOI:

10.3323/jcorr.71.213

Abstract

Acoustic emission （AE） method was used to evaluate the fracture strength of corroded steel bolt joints. AE monitoring was carried out on steel bolted joints subjected to corrosion accelerated test using NaCl solution with different duration. After the corrosion test, the tensile strength of bolted joints was evaluated. A correlation was found between the fracture strength of corroded bolted joints and cumulative AE events. Next, the relationship between the parameters of the AE waveforms and the corrosion conditions was evaluated. As a result, waveforms with a strong amplitude of the guided wave L（0, 1） mode were detected in the bolted joints with severe corrosion, and the peak frequency of AE signals tended to decrease. In addition, many AE signals with high maximum amplitude were detected in the bolted joints where corrosion had progressed. These results indicated the possibility of estimating the fracture strength of bolts from parameters such as amplitude and frequency.

Investigation of Relationship between Corrosion and Hydrogen Entry Behavior of Electro-galvanized Steel under Atmospheric Environment

Kentaro Hata, Takeshi Matsuda, Shinji Ootsuka

pp. 218-224

DOI:

10.3323/jcorr.71.218

Abstract

The effect of corrosion status of zinc coating on the hydrogen absorption behavior was investigated. Dry-wet corrosion test was conducted after applying NaCl solution to the zinc coated steel sheets. The permeating hydrogen during the corrosion test was measured by electrochemical technique. It was found that the hydrogen permeation was not observed at early stage of corrosion while significant hydrogen permeation was observed at middle stage of corrosion. Then, the hydrogen permeation decreased gradually at later stage of corrosion. In order to clarify the mechanism of this behavior, surface morphologies of corroded specimens were analyzed by Electron Probe Micro Analyzer. It was found that the hydrogen permeation was observed when the steel substrate was partially appeared, indicating that galvanic corrosion is related to the hydrogen permeation.
