%) Fatigue tests were conducted at 10 Hz in air of 40%-60% relative humidity and at 5 Hz in salt fog (3.5% NaCl solution) at 25 ℃ in MTS servohydraulic mechanical test machine. Fatigue loading was in stroke.... The axial fatigue tests were conducted under a constant amplitude sinusoidal wave loading at stress ratio of 0.1 in laboratory air and salt fog at room temperature. The results show that the yield stress......
stir welding; salt fog test; response surface methodology; corrosion rate 1 Introduction High strength AA2024 aluminium alloy, as a typical precipitation hardening aluminium alloy, is difficult..., to correlate the salt fog test parameters and the corrosion rate of AA2024 aluminium welds, a second order quadratic model was developed. The response (corrosion rate) is a function of pH value (P......

The salt spray tests of the coated samples and the substrates were carried out in a salt spray test machine. The phase composition and surface morphology of the coatings......
;Continuous salt spray test was carried out by Q-Fog salt spray chamber according to ASTM B117. The salt solution was 5% NaCl; temperature was 35 ℃; the deposition rate of salt fog was 1-2 mL/h; and pH... Accelerated corrosion tests are necessary for development and qualification of materials. At present, salt spray test is widely used in aeronautical industry. For instance, WU et al [1] carried out salt spray......
ARTICLE J. Cent. South Univ. (2019) 26: 323-330 DOI: https://doi.org/10.1007/s11771-019-4004-z Salt ions accumulation and distribution characteristics of pioneer plant species at a bauxite residue... in an abandoned BRDA in Central China. The pioneer plant species at the disposal area were identified, whilst distribution characteristics of salt ions such as Na+, K+, and Ca2+ in plant tissues......
. In the salt spray test, the colloidal silica film provides better corrosion protection than CCC film, i.e., red rust appears at 96 h on the Zn-electroplated steel sheet, at 432 h on the CCC films, and at 888 h on silica conversion coating. Key words: colloidal silica conversion film, corrosion salt spray test, rust  ......
