The new grade steel (containing anti-corrosion elements of Cr and rare earth) can find wide application in marine engineering, with further enhanced comprehensive properties via melting process improvement.
Sensitized HNSSs showed reduced corrosion resistance with increasing cold work level in both 3.5% NaCl and 0.5 M H2SO4 + 0.5 M NaCl solutions due to a reduction in the anti-corrosion elements in the matrix during the cold work-accelerated precipitation process.
Compared to the other two materials, the overall performance was better for the laser cladding Ni Cr Mo alloy coating which on one hand had optimal ratio of corrosion resistance elements and on the other hand had grain strengthening effect by laser cladding technique.
This paper proposes the combined use of SS and GFRP rebars to achieve ductile and corrosion-free elements.
FRP tube provides a corrosion resistant element, reinforcement, confinement for the concrete core, and a stay-in-place formwork.
It was detected that corrosion due to elements such as chlorine, potassium, zinc, lead and copper had caused severe material wastage in the biomass boiler with relatively low heat exchanger surface temperatures.
In Al-added alloys, the corrosion of Cr element is suppressed by the Al dissolution, and the formation of inner alumina in high Al alloys leads to the surface exfoliation.
The fate and identity of the solute (Sn) and solvent (Cu) elements following corrosion, as soluble ions or insoluble corrosion products, was investigated.
Even if only the remaining metal bulk is analysed, its composition can have changed due to preferential corrosion of certain alloying elements and the leaching phenomena.
Mortar for patch repair of damaged concrete elements by corrosion or honeycombing are extensively used.
