sacrificial metal

Sacrificial metals, for example, can be used to prevent cracking.

The sacrificial metal instead of the protected metal, then, corrodes.

A sacrificial metal embedded within a specially formulated cementitious mortar.

Sacrificial metals are widely used to prevent other metals from rusting, for example food cans.

Zinc serves as a sacrificial metal, so the steel does not rust when zinc is present. '

Electrocoagulation presents a robust novel and innovative alternative in which a sacrificial metal anode doses water electrochemically.

A simple method of protection connects the metal to be protected to a more easily corroded "sacrificial metal" to act as the anode.

Such systems generally consist of strategically located deposits of "sacrificial metals" which act as an anode to reduce corrosion of the metal being protected.

Many tests had been performed to try and determine the cause and possible protection from corrosion in boilers using distilled water, various chemicals, and sacrificial metals.

A sacrificial metal is a metal used as a sacrificial anode in cathodic protection that corrodes to prevent a primary metal from corrosion, galvanization or rusting.

This tendency can be decreased by coating the silicon carbide particles with a suitable oxide or nitride, preoxidation of the particles to form a silica coating, or using a layer of sacrificial metal.

The melted core is supposed to hit a thick layer of a "sacrificial metal" which would melt, dilute the core and increase the heat conductivity, and finally the diluted core can be cooled down by water circulating in the floor.

She glanced at the hull health indicator and saw that they were down to only a few remaining millimetres of sacrificial metal, that the chaff throwers were depleted, and that - realistically - they could withstand no more than one or two additional bursts of graser-strike. '

To incorporate nanowire technology into industrial applications, researchers in 2008 developed a method of welding nanowires together: a sacrificial metal nanowire is placed adjacent to the ends of the pieces to be joined (using the manipulators of a scanning electron microscope); then an electric current is applied, which fuses the wire ends.
