Tarnish Resistance, Corrosion and Stress Corrosion Cracking of Gold Alloys

Tarnishing, corrosion and stress corrosion cracking (SeC) of gold alloys are related phenomena. They present problems when they occur in gold jewellery, dental gold alloys and electronic devices. They are exploited, however, in the depletion gilding and finishing of gold jewellery; and in the extraction, refining and fire assaying of gold. There is still much that is not known about these pheno...

Evaluation of Selective Phase Corrosion Thickness on Nickel Aluminum Bronze Valves using Transient Eddy Current

Nickel Aluminum Bronze (NAB) is a material with marine environment applications. Under certain conditions the material can undergo selective phase corrosion (SPC), which involves the removal of particular elements resulting in a loss of material strength. Additional changes in material properties include a change in conductivity and permeability in comparison with the parent material. Transient...

Classification of corrosion defects in NiAl bronze through image analysis

Corrosion surface damage in the form of pitting and micro-cracks is observed in many metals. Cracks usually initiate from the pits and grow under cyclic stresses and eventually lead to material failure. An image analysis based on wavelet transforms and fractals was used to study the corrosion morphology of nickel aluminum bronze metal under varying corrosion conditions and applied stresses. Ima...

Corrosion Resistance Improvement of Aluminum by Hydrophobic Anodic Oxide Film

Diminishing surface wettability is an effective method to improve corrosion resistance of aluminum. Various techniques for preparing hydrophobic surface have been reported, most of which use organic coating as the final step. The key point to diminish surface wettability is to form a fine regular surface structure, and the porous type anodic oxide film (PAOF) has nano-pore structure, therefore ...
