Additionally, it eliminates the need for oversized recirculating pumps, minimizes heat-loss by reducing fluctuations in average temperature and flow rate, and lowers flow in hot water return lines minimizing erosion-corrosion problems caused by excessive velocity.
The topics include laser surface melting to repair stress corrosion cracking in weld metal, pulsed laser surface treatment of multilayer gold-nickel-copper coatings to improve the corrosion resistance of components in electronics, liquid impingement erosion resistance, modifying the surface of steel to resist slurry erosion in power plants, and laser surface remelting to improve the erosion-corrosion resistance of nickel-chromium-aluminum-yttrium plasma spray coatings.

In the investigation [2] the microstructure and erosion-corrosion behavior of a Fe-Cr-C overlay (Fe Cr C-matrix) produced by plasma transferred arc welding and its metal matrix composite (Fe Cr C-M M C) were assessed.
The combination of corrosive fluid (saliva with several enzymes and food particles) and high velocity in the oral environment results in erosion-corrosion or fretting.
The abrasion resistance of hardened KVA MSS tube and pipe is unmatched - maximizing durability, reliability and reducing erosion-corrosion failures.
Alongside the sessions, the conference will also hold workshops on various topics by corrosion experts and professionals including Total integrity management -- linking corrosion and erosion-corrosion research to industry's needs by Dr Xinming (Simon) Hu and Anne Neville, University of Leeds, School of Mechanical Engineering, UK.
The erosion-corrosion resistance of coatings is primarily dependent on their composition and microstructure, rather than on their hardness.
