Cathodic protection by impressed current or galvanic methods are in common use for the protection of corrosion in steel structures such as pipes, tanks, wharves and bridges. Both methods of cathodic protection are electrical processes that involve voltages and currents being introduced into the structures. Occasionally these facilities are situated in hazardous locations involving explosive...

Continuous Fabric Maintenance (FM) is crucial for uninterrupted operations on off-shore oil and gas platforms. A primary FM goal is managing corrosion onset across the platform surface. Currently, physical field inspections are conducted to detect and classify corrosion. These processes are subjective, costly, time-consuming, and labour-intensive. As such, they tend to be sparse in nature...

To investigate the corrosion resistance of overlapping layers between Al-5Mg thermal spray coating and heavy-duty coating, this study aims to clarify the deterioration behaviours of the cases with different boundary connection modes. The linear and ribbon defects were introduced to specimens, and the accelerated corrosion tests were performed. Besides, a laser focus measuring system was...

Use of Shipwreck Material From HMS Sirius (1790) The ability to obtain accurate measurements of corrosion rates in shallow water sites is generally limited, owing to extreme operational conditions for test rigs, the cost of experimental setups and limited time exposure of a few years. Museum conservators have authorised access to a wide range of...

This webinar features speakers discussing some of the key challenges that corrosion can present and the methods that can be used to protect key structures. Organised by the ACA VIC Branch, discussions include the work undertaken to prevent the degradation of iconic Australian landmarks including Laser Cleaning using powerful ultrashort Pulse lasers of the Sydney Harbour Bridge from Dr. Ludovic Rapp (Laser Physics Centre - Australian National University and CP based Repair of the Sydney Opera House from Ian Godson (Infracorr).

The marine environment is one of the harshest settings in terms of causing the corrosion of metal structures and components. The webinar organised by the Victorian Branch of the Australasian Corrosion Association focuses on marine coatings and technology to minimise problems caused by the corrosion of marine structures. We heard from three leading industry experts, Peter Dove (GHD), Kyle Fortune (Denso) and David Anderson (UCC) on issues and recent advances in this important area.

Thunyaluk Pojtanabuntoeng, Curtin Corrosion Centre Introduction Thermal insulations used for energy conservation and personnel protection can create an environment perfect for corrosion by forming a narrow annular space that can trap water between the metal surface and an insulation material or by acting as a wet sponge in contact with the metal surface. Once water...
