Phosmatt ‐ an alternative phosphating system

J. Le Prevost

Describes the Phosmatt phosphating system, which can be used as a pre‐treatment for the painting, coating or bonding of steel surfaces. Offers great savings in time and space…

Forward and backward‐scanning in current‐potential domain ‐ a candidate sensor for surface galvanic strain

D. Mukherjee, G.T. Parthiban, S. Muralidharan, D. Jayaperumal, C. Srividyarajagopalan

Three types of alloys have been chosen, and subjected to three different varieties of macro‐strains, e.g. corrosion‐pittings in a high strength low‐alloy, sensitization‐induced…
